20100172718 | Fastener with Shaving Inhibitor - A fastener with shaving inhibitor for fastening a material such as a metal sheeting panel to a substrate such as metal or wood. The fastener has a notch angled leftwardly with respect to an axis of the fastener, the notch having a first end and a second end, a leading face and a trailing face, each face having outer edges and a common edge at their intersection. At least one of the leading and trailing faces may be substantially planar but may have other shapes, such as concave. Leftwardly angled notch with faces having outer edges may attract and then cut shavings formed from material being installed, thereby reducing the quantity and/or length of shavings, prolonging the life of the material or the structure to which the material is fastened. | 07-08-2010 |

20100310337 | LOOSE RESISTANT BOLT STRUCTURE - A loose resistant bolt structure is disclosed which includes a bolt unit and a buffer portion. The bolt unit includes an intermediate portion, a head portion at an end of the intermediate portion, and a threaded portion at an opposite end of the intermediate portion. The buffer portion surrounds the threaded portion and is located adjacent to an end of the bolt unit to form a distinct pitch on the threaded portion. When the threaded portion engages with a nut, the buffer portion is drawn, shrunk or twisted, producing elastic stress and torsion force, thereby securing the threaded portion to the nut and resisting loose therebetween, and will be able to avoid an inner thread of the nut caused damage during assembly. | 12-09-2010 |
20110299958 | ANTI-LOOSEN SELF-TAPPING SCREW - The anti-loosen self-tapping screw includes a head, rod and a thread. The rod extends from the head and an end of the rod forms a conic tapping tip. The thread is around the rod from the tapping tip to a position near the head. The thread is provided with an axial groove to cut off the thread. The divided ends along one side of the groove are separately provided with expanded portions whose cross-sections are expanded. | 12-08-2011 |

20100247268 | SCREW CONNECTION FOR A FIXED CONNECTION OF TWO ASSEMBLIES - Screw connection for a fixed connection of two assemblies which are mounted to each other in a variable position, using a connecting member penetrated by a screw. The connecting member is mounted between the assemblies by means of a self-cutting screw penetrating the connecting member and one of the assemblies, which screw is grooving its thread into both parts in such a way that, starting from a stable end position of the one assembly and the connecting member, the screw is adapted to be screwed into the connecting member as well as into the one assembly by means of thread grooves such that, by means of the self-cutting thread of the screw, the connecting member and the one assembly are held in a fixed position with respect to each other, and the other assembly is fastened directly to the connecting member. | 09-30-2010 |
20110262246 | Threaded Rod - A threaded rod comprises a single coarse thread having flattenings on opposite sides forming thread sections on opposite sides. At least one of the thread sections on one side of the threaded rod is omitted. | 10-27-2011 |
20130294865 | ONE PIECE HYDRAULIC DISC BRAKE CALIPER WITH ONE WAY PLUMBING - A hydraulic disc brake caliper that includes a housing that has first and second side portions and first and second end portions that cooperate to define a braking opening. The housing also includes first and second piston receiving openings and first and second fluid openings. The caliper also includes a bolt received in the second fluid opening that includes a shaft having a portion of a fluid path defined in the outer surface thereof that includes at least one channel and at least one reduced diameter portion. The fluid path extends from the first fluid opening to the second fluid opening. The at least one channel and the at least one reduced diameter portion are part of the fluid path and are in fluid communication between the first and second piston receiving openings. | 11-07-2013 |
