Description
- This application is a continuation of U.S. application Ser. No. 15/487,805 filed Apr. 14, 2017, the disclosure of which is hereby incorporated in its entirety by reference herein.
- The present invention relates generally to fasteners and more particularly to a three-point fastener for transmitting torque from a tool to the fastener.
- Fasteners are used in numerous applications to attach various components together. Typically, a fastener has at least a threaded portion and one or more bearing surfaces attached thereto. The bearing surfaces are designed to receive torque from a tool, such as a socket or wrench, which is used to tighten or loosen the fastener. In a conventional fastener, such as a nut, the fastener may have internal threads and six bearing surfaces oriented in a hexagon shape around the internal threads. However, other fasteners may have external threads, such as bolts and screws.
- The most common shape of a tool to apply torque to threaded fasteners is a hexagon or hexagon-like geometry socket. Accordingly, many fasteners have a hexagon shape. Applying torque with a hexagon or hexagon-like geometry socket to fasteners creates contact between the socket and fastener at six places, namely, at or near each corner of the hexagon fastener. In contrast, a standard open-end wrench applies torque to fasteners at two places, namely, at opposite corners of the hexagon fastener. This common usage of open-end wrenches with hexagon fasteners demonstrates the strength that exists in hexagon fasteners at the torque bearing surfaces.
- To meet ever increasing global demands for energy efficiency, automobile manufacturers have expressed the need to reduce the mass of vehicles to help meet government requirements for increasing fuel efficiency. The inventor believes the design of fasteners can be improved to lower weight, while maintaining the highest industry standards for durability and function.
- In one embodiment, a fastener comprises a threaded portion and a bearing portion. The bearing portion includes three bearing surfaces designed to receive torque from a tool and transmit torque to the threaded portion. Each bearing surface includes two adjacent sides with an edge disposed between them. The bearing portion also includes three non-bearing surfaces located between each of the bearing surfaces.
- The invention can be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like referenced numerals designate corresponding parts throughout the different views.

Bearing portion 106 may also include three non-torque bearing surfaces 120, 122, 124. The non-torque bearing surfaces 120, 122, 124 may not be intended to receive and transfer torque from a tool to the threadedportion 102. The non-torque bearing surfaces 120, 122, 124 may, however, incidentally receive and transfer torque from a tool to the threadedportion 102 even if the non-torque bearing surfaces 120, 122, 124 are not intended to do so. - The non-torque bearing surfaces 120, 122, 124 may be located adjacent to and between the
torque bearing surface torque bearing surface portion 106. -
Fastener 100 may have a reduced mass compared to a standard fastener of similar size designed for the same application asfastener 100. The reduce mass offastener 100 may be due to the presence of the non-torque bearing surfaces 120, 122, 124 in place of torque bearing corners that would be located on standard fasteners. For example, the mass reduction offastener 100 over an M12×1.75 thread×19.0 mm across flats×12.0 mm high standard hexagon nut would be between 9-11%, and preferable approximately 11% plus or minus 0.5%. In grams mass, this is a reduction from 18.3 to 16.9 grams. -
FIG. 2 shows another embodiment of an improved fastener.Fastener 200 may have the same features and components asfastener 100.Fastener 200 may include angles atedges fastener 200 may still be driven by standard socket tools, such as a hexagon socket or a 12 point configuration socket. For example, the angles atedges fastener 200 may be 126 to 130 degrees. - The increased angles at
edges fastener 200, in comparison to the angles offastener 100, may be caused by recessed regions 208 a_r, 208 b_r, 210 a_r, 210 b_r, 212 a_r, 212 b_r of thetorque bearing sides edges FIG. 2 . The recessed regions 208 a_r, 208 b_r, 210 a_r, 210 b_r, 212 a_r, 212 b_r of the torque bearing sides are disposed inwardly from an imaginary plane defined by the remainder of thetorque bearing sides edges edges fastener 100 because the initial contact between a standard socket tool and the recessed regions 208 a_r, 208 b_r, 210 a_r, 210 b_r, 212 a_r, 212 b_r of the torque bearing sides occurs along a generally parallel plane to the initial contact area, which is significantly larger than the initial contact area withfastener 100. As a result, the initial pressure generated by the applied torque is less and may cause less deformation of thefastener 200. The recessed bearing surfaces and increased angle atedges -
FIG. 3 shows another embodiment of an improved fastener.Fastener 300 may have the same features and components asfasteners Fastener 300 may include modified torque bearing surfaces 308, 310, 312 and modified non-torque bearing surfaces 320, 322, 324, as compared tofasteners Fastener 300 may still be driven by standard socket tools, such as a hexagon socket or a 12 point configuration socket. Infastener 300, torque bearing surfaces 308, 310, 312 and non-torque bearing surfaces 320, 322, 324 may be curved and may be smoothly contoured into each other in order to reduce the mass offastener 300. As shown inFIG. 3 , the torque bearing surfaces 308, 310, 312 adjacent to non-torque bearing surfaces 320, 322, 324 have been reduced in size such that there is a smooth transition to the non-torque bearing surfaces 320, 322, 324 instead of a sharp corner, as inFIG. 1 . Similarly, non-torque bearing surfaces 320, 322, 324 have been curved to smoothly transition to the torque bearing surfaces 308, 310, 312. -
Fastener 300 may have a reduced mass compared to a standard fastener of similar size due to the modified torque bearing surfaces 308, 310, 312 and modified non-torque bearing surfaces 320, 322, 324. For example, the mass reduction offastener 300 may be approximately 17% compared to a standard fastener of similar size designed for the same application asfastener 300. The size reduction and/or curvature of torque bearing surfaces 308, 310, 312 and non-torque bearing surfaces 320, 322, 324 may be adjusted to increase or decrease the mass reduction offastener 300. -

Infastener 400, torque bearing surfaces 408, 410, 412 and non-torque bearing surfaces 420, 422, 424 may be angled toward each other in order to reduce the mass offastener 400. As shown inFIG. 4 , the torque bearing surfaces 408, 410, 412 adjacent to non-torque bearing surfaces 420, 422, 424 have been reduced in size and angled such that there is a smooth transition to the non-torque bearing surfaces 420, 422, 424 instead of a sharp corner, as inFIG. 1 . Similarly, non-torque bearing surfaces 420, 422, 424 have been angled to smoothly transition to the torque bearing surfaces 408, 410, 412. Non-torque bearing surfaces 420, 422, 424 may includeedges -
Fastener 400 may have a reduced mass compared to a standard fastener of similar size due to the modified torque bearing surfaces 408, 410, 412 and modified non-torque bearing surfaces 420, 422, 424. The mass reduction offastener 400 may be less than the mass reduction offastener 300 due to the angles of torque bearing surfaces 408, 410, 412 and non-torque bearing surfaces 420, 422, 424. The angles of torque bearing surfaces 408, 410, 412 and non-torque bearing surfaces 420, 422, 424 may be adjusted to increase or decrease the mass reduction offastener 400. -

Similar tofastener 300,fastener 500 may include modified torque bearing surfaces 508, 510, 512 and modified non-torque bearing surfaces 520, 522, 524, as compared tofasteners - Similar to
fastener 100, eachtorque bearing surface edge Fastener 500 may be designed and shaped to be driven by standard socket tools, such as a hexagon socket or a 12 point configuration socket. Accordingly, the angle atedges edges fastener 500 to match a standard hexagon shaped socket. -
Fastener 500 may have a reduced mass compared to a standard fastener of similar size due to the presence of the non-torque bearing surfaces 520, 522, 524 in place of torque bearing corners that would be located on standard fasteners. For example, the mass reduction offastener 500 over an M12×1.75 thread×18.0 mm across flats×12.0 mm high standard hexagon nut would be approximately 36%. In grams mass, this is a reduction from 17.5 to 11.1 grams. -
