Abstract
An interlocking fastener assembly has an insertion member, a receiving member, and a fastener. The receiving member has a guide opening with pockets which receive a polygonal locking portion of the insertion member during assembly. The locking portion has tapered sides and apexes to self center the insertion member. The guide opening pockets and sides allow limited rotation of the insertion member in the receiving member until a mechanical lock is created preventing further rotation of the insertion member. The mechanical lock allows a fastener to be threaded onto the insertion member without the use of a backup tool.
