ABSTRACT:
A fastener system is providing having a male threaded member and a female threaded member with arrangements for achieving a locking connection between the parts to prevent relative rotation of the parts due to vibration. In an embodiment of the invention, the male member is comprised of a folded over plate with threads formed on an end portion, either the folded end or the free ends, or both, which is engageable into the female member. In another embodiment, the male member is formed of two pieces overlying one another with threads formed on the overlying portions. The thickness, width and number of threads on the male member can be selectively determined to provide the desired torque for rotating the two members relative to one another. The male member can be configured as a linear member, an offset member, as a clevis, or other non linear shapes, which shapes are particularly easy to accomplish by forming the male member of two legs either by folding or as separate pieces.
