Field of the Invention This invention generally relates to a method for securing a cover to a support without fasteners as seen and the components and tools used in the method . The method, member and tool are particularly advantageous when used to secure a deck board to a support or to secure a trim board to a support. [Prior Art] It is known to fix a cover to a support such as a joist, such as a nail or a screw. Typically, the fastener is placed through the exposed surface of the cover and into the support to allow the fastener head to be viewed. Recently, there has been a need for a "hidden" system that secures the cover to the support without leaving visible fasteners on the exposed surface of the cover. The conventional method of concealed system involves first drilling a perforation and a countersunk hole in the cover, and then placing a fastener through the cover and into a support structure in the counterbore The head of the fastener is recessed below the surface of the cover. A plunger is disposed in the counterbore to hide the head of the fastener from view. This method requires a first The tool pre-drills a perforation and countersink, then inserts the fastener with a second tool and then inserts the plunger. These traditional methods are time consuming. Other concealed fastener systems require expensive preparation of system components For example, if a rail is installed on the grille, the groove for the fastener is drilled on the cover in advance -5 - 200918770, or the cover is adhered to the grille. The hidden cover system must be installed from the bottom. This is - consumption In addition, the widespread use of composite materials creates special problems in achieving hidden systems. [Summary of the Invention] Therefore, a sad form of the present invention is a one-of-a-kind A method of fastening a plate to a support member, wherein a hole is formed in the cover plate when the mechanical member is driven through a portion of the cover plate in a single operation. Another aspect of the invention is a A method of fastening to a support member with a mechanical fastener plate wherein the counterbore is formed after the mechanical member is disposed at a predetermined depth within the cover plate and a specially constructed plunger is Inserted into the counterbore. Another aspect of the invention is a driver tool for rotating a mechanical fastener that cuts a countersunk fastener in a single operation at a predetermined depth. A more detailed description of the presently preferred embodiments of the invention is provided herein. Briefly, a method of securing a cover to a support provides a plurality of substantially identical plungers having cover The material is the same as the material composition. The cover plate is disposed on the support member and is fastened to the positioning by the fastener. The fastener is driven to enter the support member through the cover plate to a predetermined depth. Driven in a fastener. Some expensive and efficient fastener-fastening of the counter-head will drive the cover to the cover and partially move the component-containing fasteners through the cover - 6- 200918770 While doing the opposite, a counterbore is formed in the cover plate above the si portion of the fastener. A plunger is then placed in the counterbore and placed to allow the cover And the outer surface of the plunger is coplanar. The counterbore is preferably formed by the fastener head when the fastener head is driven to a position between opposite faces of the cover. The firmware is driven by a driver and the countersink is formed when the driver and the fastener head are coupled to each other. The counterbore has a diameter 'which is slightly smaller than the fastener head. The cover is preferably selected from a natural wood veneer comprising a polymer composite and/or honeycomb PVC. , a natural wood modified board or a modified board comprising a polymer 'composite and/or honeycomb PVC. Preferably, the plunger has a reduced portion that is initially inserted into the cover. The plunger has the same material as the cover and, in some embodiments, a tapered shape for a given sharpened angle of a given material. The plunger in one embodiment has an enlarged cylindrical portion and a coaxial reduced cylindrical portion. A driver for the fastener includes a generally elongate body including opposite first and second ends. A tool engagement portion at the first end is designed to secure the driver to a tool such that a rotational torque and an axial force can be applied to the drive. A fastener bit at the second end is constructed to mechanically intermesh with the head of the fastener. The fastener bit has a profile selected from the group consisting of a straight shape, a cross shape, a TorxTM shape, a square shape, a polygonal shape, and a key groove shape. A spring loaded washer is mounted to the body and engages the cover axial direction 200918770 to limit the penetration depth of the fastener. The spring is preferably a collapsible coil compression spring. The gasket is composed of a sturdy or anti-1 marr-resistant material. The body of the drive has a pair of longitudinally spaced apart annular shoulders. The spring engages a shoulder and biases the washer against the second shoulder. [Embodiment] Referring to Figures 1A to 1F, a plunger fine machining method for fastening a cover 1 to a support member 1 2 is shown in a representative continuity step. The method shown can be used to fasten a cover panel made of composite wood panels to a support grid. The plunger fine machining method can also be used in applications related to a variety of other applications, including decorative finishing. Referring to Figure 1A, a drive 20 is housed in a collet 40 of a drill or other torque tool (not shown). The drill end of the driver engages the head 52 of the fastener 50. As shown in Figures 1 b through 1D, the fastener is progressively driven through the composite panel into the grid until the head reaches a predetermined depth of the top surface 14 of the cover. While the fastener is being driven, the head of the fastener is constructed to form a counterbore 16 in the composite plank above the head (see Figure 8). In a preferred method, the counterbore is about 6.35 mm to 7.94 m. Referring to Figures 1E through 1F', a specially constructed plunger 6 is removed from the same set of plungers. The selected plunger 6 is inserted into the counterbore 16 . The plunger is made of the same material as the composite wood panel and is constructed such that its top S 62 is snugly engaged with the upper wall of the countersink. The township -8 - 200918770 head 70 or similar tool is used to tap the plunger until it is flush or coplanar with the top surface 14 of the cover (or composite). The method described above may be repeated for a plurality of fasteners at spaced locations on the cover panel to secure the cover panel to the grille that has been spaced apart to date. Preferably, a bag contains a plurality of substantially identical plungers. These plungers are selected for use in the counterbore thus formed and are knocked to position. The method uses a driver 20 to drive the fastener 50 partially through the cover plate 10 and into the support member 12. A preferred fastener is a TrapEase® 11 overlay panel screw manufactured by OMG Corporation of Agawan, MA. The fastener 50 includes a threaded portion that bites into the composite/plastic material when the thread is cut into the cover and thereby removes material. The head 52, and in particular the periphery and bottom side of the fastener head, is constructed to remove material from the cover by shearing strands and debris and to grasp when the head sinks into the cover The cover is secured to form a countersunk hole 16 in a single operation. A single operation means that the counterbore 16 is formed in the cover 1 at the same time that the fastener is driven through the cover - the counterbore is a hole in the cover having A cross-sectional width that is greater than the maximum cross-sectional width of the fastener threads 54. Typically, the counterbore has a diameter that is the same as or slightly smaller than the diameter of the fastener 52 used. For some materials, the counterbore may have a slightly smaller diameter due to the elastic relationship of the composite. It should be noted that the method and components can be used in other environments and other combinations or sequences are used and all such uses are part of the present invention. The cover (e.g., a cover panel) is typically supported on a structure such as a skeleton or support member such as a decorative grille, a cross panel and a grille. This support structure can be constructed in a conventional manner. A first cover is placed on the support (a representative grid in Figure 1). The cover has an outer surface 14 and an opposite support surface 18 that are viewed from the outside by a user and are adjacent to the grids. Typically, the cover panel 1 will be secured to each of the grids 12 using two spaced apart fasteners (e.g., overlay screws). The location of the fasteners is marked on the cover. A hole spacer (not shown) can be used to provide consistency of the fastener relative to the setting of the cover. In one embodiment, the aperture spacer is a plate having one or more perforations and an arm member projecting at an angle from one end of the plate. The arm member is disposed proximate a longitudinal edge of the cover plate for vertically aligning the hole spacer with the longitudinal axis of the cover plate. When aligned, the perforations of the board correspond to the position at which the fastener will be placed on the cover. The perforated locations can be marked on the cover such that the fastener can be driven into the cover at the marked location. Alternatively, the hole spacer can be retained adjacent to the cover and the fastener can be driven through the perforation or a drill bit can be driven through the perforation. The driver 20 is coupled to a drill chuck 40 as shown in Figures 1A through 1D. A fastener head 52 even engages the fastener bits 2 2 of the actuator. An axial force and a rotational force are applied to the fastener to drive the fastener tip 56 through the cover at a previously marked position. When the fastener is driven through the cover, the counterbore 16 is formed - -10-200918770. The counterbore is preferably formed from the fastener as described above. However, the countersink may be formed by a material removal section or by a combination of the fastener and the material removal section. The driver body between the driver portion and the fastener bit optionally includes a material removal section (not shown). The material removal section has a second cross-sectional width which is preferably greater than the cross-sectional width of the fastener bit. In some embodiments, the material removal section can remove material from the cover to form a countersink formed in the cover or to expand or "clean". Preferably The material removal section may include one or more flutes for providing a cutting edge and an outlet passage for the removed cover material. The driver 20 preferably has a stop member 3〇 When the stopper 3 is in contact with or engaged with the cover plate with a sufficient force defined by a predetermined depth, the axial force is used by the fastener bit and the fastener head The detachment of the portion is interrupted. The drive is then removed from the counterbore. The procedure for driving the fastener and forming the counterbore is advantageously implemented in a single operation 'the fastener bit 22 remains with the tight The firmware heads 5 2 are intermeshing. A plunger 6 is disposed within the counterbore as shown in Figure 1 F. The plunger 60 will be specially constructed as described below. Typically, for aesthetic purposes 'The plunger will closely match the appearance of the outer surface of the cover. The procedure is repeated as needed to secure the first cover to the remaining grille. A second cover is placed on the grill adjacent the first cover, the position of the fastener being marked On the second cover, the fasteners are driven through the second cover into the grid as described above and a plunger is placed -11 - 200918770 in each counterbore. One embodiment is illustrated in Figures 5 to 7. The actuator includes a generally elongate body 24 that includes opposite ends. One end of the body includes a tool engagement portion 26 that is designed to secure the drive to one A tool, such as a drill bit, allows rotational torque and axial force to be applied to the driver. The other end of the body includes the fastener bit 22. The fastener bit 22 is constructed to mechanically engage a head of a fastener The portions are intermeshing such that a user can apply axial force and rotational torque to the fastener. The fastener bit 22 can be any configuration that can mechanically intermesh with the head of a selected fastener. Such as a glyph, ten The shape 'T 〇r X TM shape, square (as shown), polygonal and keyway shape. In an embodiment (not shown), the fastener bit is removably attached to the driver. In this embodiment The fastener bit can be replaced when worn or when the driver is intended to be used on a different head design fastener. Preferably, the stop member 30 limits the drive tool into the cover interior. Penetration, thereby limiting the depth of penetration of the fastener and the depth of the counterbore. The stop may optionally include a rotating member such as a bearing. The rotating member allows the drive to continue to rotate (with the cover) The stop of the plate contact is excluded) until the desired depth of the fastener is reached, thereby reducing the marking of the cover. Many types of fastener designs can be used with the present invention. Factors such as depth of the countersink and thickness of the cover are taken into account. Next, the length of the fastener is selected to provide that the cover is mechanically fastened to the support. Naturally, the -12-200918770 fastener head can intermesh with the fastener bit. Some of the advantageous fasteners are TrapEase® and TrapEase® II overlay screws manufactured by OMG in Agawan, MA. In Figures 5 through 7, the disclosed driver assembly 20 is designed to drive a 'fastener (such as, for example, a TrapEase® II overlay panel screw manufactured by OMG, Inc., Agawan, MA) to A composite cladding material. In a preferred form, the head 52 of the fastener has a diameter of 6.60 mm. The driver has a square drive bit 22 and is designed to drive the cover panel screws such that a counterbore of a predetermined depth can be made by the head of the fastener. The upper shank 26 has a hexagonal shape for retention in the collet of the torque drill. A washer 38 is made of Delrin® and is pressed against the lower cylindrical shank. The inner diameter of the pad 38 is larger than the shank on which it is held for sliding and rotating longitudinally. Annular shoulders 34 and 36 are formed at opposite ends of the lower cylindrical shank for retaining and limiting axial movement of the gasket. Referring to Figures 7A and 7B, a collapsible conical compression spring 32 is engaged between the end of the shank and the rim to bias the washer toward the drive end of the drive. The pad engages the top surface of the cover and allows rotation of the bit end and keeps the remainder stationary. The latter's gasket engagement minimizes motion and acts like a stop. The fastener then engages the driver bit 22 through the telescopic head and is twisted. During this driving process, the pad compresses the spring 32 and is urged toward the shoulder of the handle, which fixes the depth of the head to the facing screw and the depth of the counterbore, and thus further drive is terminated. -13- 200918770 The washer 30 is rotated independently of the driver such that the surface of the cover panel is not worn during the driving and setting of the fastener, the fastener will be set for a given The preset depth of the application. A plunger 60 is inserted into the counterbore to prevent the fastener from being seen. Preferred plunger embodiments are shown in Figures 2 A ' 2 Β ' 3 A ' 3 Β, 4A and 4D. A preferred configuration of the plunger is a portion having a cylindrical shape and a cylindrical portion, such as plungers 60A, 60B and 60C. The enlarged portion has a substantially uniform diameter which is the same as the diameter of the counterbore. A tapered transition portion 64 is inserted with a reduced cylindrical portion 66. The outer end face 68 will be coplanar with the top surface 14 of the cover when installed. The inner end face 69 engages or abuts the top end of the head 52 of the fastener. The reduced portion facilitates initial insertion into the counterbore and is used to automatically center the plunger. . In addition, the reduced portion 66 provides an annular recess that can receive any remaining material formed over the head during the drilling process. The plungers 60A' 60B and 60C are designed to be sized to be used with the above-described facing screws and a driver having a pre-5's 77.9 mm depth. The dimensions of the particular plunger (in mm) are listed in Table I below.
