Definitions
- Nuts are internally threaded fastening members commonly used to retain and or deliver load to an externally threaded fastener. Nuts typically have an external geometry that will allow rotational coupling with a torque input device or machine.
- Self-reacting nuts are typically comprised of an inner sleeve, outer sleeve and washer.
- Self-reacting fasteners such as the HYTORC Nut use the washer as a reaction point for the application of input torque to the outer sleeve.
- the outer sleeve functions as the nut while the inner sleeve becomes an extension of the stud and is rotationally coupled with the washer. This rotational coupling prevents sliding motion between the inner sleeve and stud threads during the application of torque to the outer sleeve.
- Self-reacting nuts with the same external geometry as conventional nuts suffer from higher bearing surface stresses. The bearing surface stresses are higher because the outer sleeve inside diameter is increased to allow space for the inner sleeve causing a thinner wall thickness than standard nuts.
- self-reacting three-piece mechanical tensioner fasteners such as the HYTORC NUT
- self-reacting three-piece mechanical tensioner fasteners include an outer sleeve, inner sleeve and washer.

- the outer sleeve functions as the nut while the inner sleeve becomes an extension of the stud and is rotationally coupled with the washer. This rotational coupling prevents sliding motion between the inner sleeve and stud threads during the application of torque to the outer sleeve.
- Self-reacting nuts with the same external geometry as conventional nuts suffer from higher bearing surface stresses. The bearing surface stresses are higher because the outer sleeve inside diameter is increased to allow space for the inner sleeve causing a thinner wall thickness than standard nuts.
- 012-021/PCT2 - DOLAN 2 three-piece mechanical tensioner fasteners typically have spline, hex or square features to allow torsion coupling with the reaction member of the torque input device. This is achieved with machined rotational interferences between two parts. The interference is typically created with a male and female engagement between any two mating features that prevent rotation between the two parts.
- Three-piece mechanical tensioning stud devices are also known. They consist of a stud, nut and washer.
- the stud has external threads on both ends. Under the upper thread the stud will also have a spline or other geometry to create a rotational coupling with the inner diameter of the washer.
- the topside of the stud will also have a spline or other geometry to allow rotational coupling with the reaction shaft of the torque input device.
- the nut is internally threaded to mate with the threads on the topside of stud.
- the nut will have a spline or other geometry to allow the introduction of torque from torque input device.
- the washer has an internal geometry that will mate rotationally with the spline or other geometry under the top thread of the stud.
- the present invention has therefore been devised to address these issues.
- an apparatus for use with a threaded fastener including:-
- 012-021/PCT2 - DOLAN 3 an inner sleeve member having an internal surface threadedly engagable with the fastener and a tapered external surface;
- an outer sleeve member having an inversely tapered internal surface rotatably engagable with the tapered external surface of the inner sleeve member.
- the invention allows for an increased load bearing surface area between the inner sleeve member, which is clamped, and the outer sleeve members without increasing the overall diameter of the apparatus; a three dimensional load bearing surface area rather than a conventional two dimensional plane; more efficiently and evenly distributed load stress distribution over the load bearing surface area; higher torsion strength; and apparatus with lower mass, dimensions and volume.

- Apparatus 1 has an inner sleeve member 100 and an outer sleeve member 200 and is used with, by way of example, a threaded stud 300.
- Inner sleeve member 100 is rotatably and threadedly engagable with stud 300; rotatably and taperedly engagable with outer sleeve member 200; and non-
- 012-021/PCT2 - DOLAN 5 rotatably engagable with an action portion of a torque input device.
- Outer sleeve member 200 is non-rotatably engagable with a reaction portion of the torque input device; and rotatably and taperedly engagable with inner sleeve member 100.
- Inner sleeve member 100 when rotated by the action portion of the torque input device, applies a load to stud 300 to close a joint (not shown).
- Inner sleeve member 100 is an annular body and, as shown in FIGs. 1 and 2, formed as a sleeve. It has an inner surface 1 10 with an inner helical thread means 120 engagable with an outer surface 310 with an outer helical thread means 320 of stud 300. It has an outer surface 1 1 1 with a cylindrical formation 121 which is rotatably engagable with an inner surface 210 with a cylindrical formation 220 of outer sleeve member 200. It further has a lower surface 1 13 which is rotatably engagable with inner surface 210.
- Cylindrical formation 121 is shaped as an inverted frustum of a stepped cone which has a tapered or conical appearance from the bottom up. Each step on outer surface 1 1 1 is progressively smaller from top to bottom.
- An external hollow cylindrical feature is removed from the outside of inner sleeve member 100 at a shallow depth. Successive external hollow cylindrical features are removed at regular length and width intervals. Each successive feature starts where the preceding feature stops. The geometric pattern of removed external cylindrical features continues until space restricts the addition of another internal cylindrical feature.
- Inner sleeve member 100 further has an upper surface 1 12 with a coupling means 130 which may be formed by a plurality of bores extending in an axial direction and spaced from one another in a circumferential direction. Coupling means 130 non-rotatably engages with the action portion of the torque input device.
- Outer sleeve member 200 is an annular body and, as shown in FIG. 3, formed as a sleeve. It has inner surface 210 with cylindrical formation 220 which is rotatably
- Coupling means 230 is formed by a plurality of outer spines extending in an axial direction and spaced from one another in a circumferential direction. Coupling means 230 non-rotatably engages with inner spines of a reaction portion of the torque input device.
- Cylindrical formation 220 is shaped as a frustum of a stepped cone which has a tapered or conical appearance from the top down. Each step on inner surface 210 is progressively smaller from top to bottom.
- An internal cylindrical feature is removed from the inside of outer sleeve member 200 at a shallow depth. Successive internal cylindrical features are removed at regular length and width intervals. Each successive feature starts where the preceding feature stops. The geometric pattern of removed internal cylindrical features continues until space restricts the addition of another internal cylindrical feature.
- Stud 300 has a cylindrical shape with outer helical thread means 320 for mating with inner helical thread means 120 of inner sleeve 100.
- An end 312 of stud 300 has a coupling means 314 which may be formed by a polygonal formation 330, which in this case is a hexagon shape. Polygonal formation 330 allows for rotational coupling with the torque input device.
- Second coupling member 150 further has a lower surface 163 which rests on an upper surface of the joint.
- Lower surface 163 may be substantially rough and may be made in many different ways, for example by a plurality of ridges, ripples or teeth.
- the stepped conical fastener geometry of apparatus 1 creates tensile load in stud 300 by the mechanical sliding action through the helical inclined plane between stud threads 320 and inner sleeve member threads 120.
- the sliding helical thread action is created by using the torque input device to apply rotation under torque to inner sleeve member coupling means 130 while reacting the
- Inner sleeve member coupling means 130 may be formed by any suitable geometry or used with other means or features for rotationally coupling with the torque input device such as gear teeth, hex, double hex, castellation or any other common geometry that allows rotational coupling.
- hex geometry shown in FIG. 5 as 530 is hex geometry shown in FIG. 5 as 530.
- Outer sleeve member coupling means 221 may be formed by any suitable geometry or used with other means or features for rotationally coupling with the torque input device such as gear teeth, hex, double hex, castellation or any other common geometry that allows rotational coupling.
- One possible alternative is hex geometry shown in FIG. 6 as 621 .
- the quantity, dimensions, geometries and intervals of removed external (inner sleeve member 100) and internal (outer sleeve member 200) cylindrical features may vary to optimize characteristics of apparatus 1 , such as, for example, stress biasing, depending on the application.
- FIG. 2 shows inner sleeve member 100 with four external cylindrical features removed at regular length and width intervals.
- FIG. 3 shows outer sleeve member 200 with four internal cylindrical features removed at regular length and width intervals. As shown in FIG. 7, varying the quantity, dimensions, geometries
- 012-021/PCT2 - DOLAN 8 and intervals from one removed external and internal cylindrical feature to the next varies the nominal angles, step heights and step widths of an outer surface 71 1 with a cylindrical formation 721 and an inner surface 710 with a cylindrical formation 720.
- the step length may be sized infinitely small to create a nearly smooth taper.
- External portions of inner sleeve member 100 and internal portion of outer sleeve member 200 may be removed in one step to form smooth conical surfaces, respectively.
- FIG. 8 shows an outer surface 81 1 with a cylindrical formation 821 and an inner surface 810 with a cylindrical formation 820 with mating faces of varying vertical spacing, or step heights. This allows movement on selective steps only as other steps are loaded. Plastic deformation allows vertical movement therefore strategically biasing stress distribution across each stepped face. In other words, increased clearance or spacing between mating faces of inner and outer sleeve members 100 and 200 allow for radial expansion during loading.
- FIG. 9 shows an outer surface 91 1 with a cylindrical formation 921 and an inner surface 910 with a cylindrical formation 920 with mating faces of varying step face angles. This promotes more evenly and controlled biasing stress distribution across the steps.
- either or both inner and outer sleeve members 100 and 200 may have stepped vertical surfaces with varying pitch angles to bias stress to selective horizontal stepped surfaces.
- FIG. 10 shows outer sleeve member 200 having internal features at bottom that couple with similar mating external features added to stud 300. These may include splines, knurls, hex, slots, double hex or other geometry. They allow axial translation of stud 300 but couple rotational movement of outer sleeve member 200 and stud 300. Both coupling means 314 formed of polygonal formation 330 and the necessity to couple this hex with the reaction member of the torque input device are no longer necessary. Internal spline 1040 and mating external spline 1041 form a spline interface between outer sleeve member 200 and stud 300, respectively.
- apparatus 1 includes a nut (inner sleeve member 100) and a washer (outer sleeve member 200).
- the standard bolting flat surface nut and washer interface is changed.
- the torque reaction point is moved upwards, as compared to conventional three-piece fasteners.
- Apparatus of the present invention utilize the concept of conventional three-piece fasteners, which allows for surface conditioning of the outer sleeve to prevent galling, leveraged with a conventional nut and washer arrangement, which retains radial strain such that the inner sleeve may be surface conditioned with minimal risk of fracture.
- the invention allows for an increased load bearing surface area between the inner sleeve member, which is clamped, and the outer sleeve members without increasing the overall diameter of the apparatus; a three dimensional load bearing surface area rather than a conventional two dimensional plane; more efficiently and evenly distributed load stress distribution over the load bearing surface area; higher torsion strength; and apparatus with lower mass, dimensions and volume.
- FIGs. 1 1 -14 shows an apparatus 1 101 for torsionally coupling a threaded fastener 1 1 10 and a torque input device 1 102 in accordance with an embodiment of the present invention.
- Apparatus 1 101 has a first coupling member 1 103 with a tapered external surface 1 104 and a polygonal formation 1 105; and a second coupling member 1 1 13 having an inversely tapered internal surface 1 1 14 and a polygonal formation 1 1 15 non-rotatably engagable with tapered external surface 1 104 of first coupling member 1 103.
- apparatus 1 101 torsionally couples torque input device 1 102 and threaded fastener 1 1 10 of the kind having a shank 1 1 1 1 with a tapered axial bore 1 1 12 at one end.
- Apparatus 1 101 includes coupling member 1 103 having inversely tapered external surface 1 104 non-rotatably engagable with tapered axial bore 1 1 12.
- FIGs. 1 -10 generally applies to the quantity, dimensions, geometries and intervals of removed external (first coupling member 1 103) and internal (second sleeve member 1 1 13) polygonal features of FIGs. 1 1 -14.
- first coupling member 1 103 first coupling member 1 103
- second sleeve member 1 1 13 polygonal features of FIGs. 1 1 -14.
- the interface between inner and outer sleeve members 100 and 200 is cylindrical and smooth thus allowing relative rotation.
- first and second coupling members is polygonal and angled thus no relative rotation is possible.
- a conical geometry for torsional coupling of a threaded fastener and a torque output device yields a better load stress distribution.
- a stepped 12-point hole in the top surface of the stud is used for torsion coupling with a three-piece mechanical stud-tensioning device and/or an apparatus for use with the stud.
- An internal 12-point feature is placed in the top of the stud at a shallow depth.
- Successive 12-point features are progressively added at smaller 12-point sizes each at shallow depths and each starting where the preceding 12-point stopped.
- the pattern of decreasing 12-point geometry will decrease until space restricts the addition of another 12 point.
- a shaft of the torque input device with external matching features for each of the steps will allow for evenly distributed stress distribution and high torsion strength while decreasing the mass and volume of the studs.
- the 12-point feature can be substituted with any geometry that will prevent rotation between the two parts, such as the hex in
- step depth can be sized infinitely small to create a smooth taper.
- Mixed step sizes and geometries can be used to optimize production of such a coupling.
