ABSTRACT:
A screw threaded fastener comprising a first member with an external screw thread and a second member with a corresponding internal screw thread. One of said first and second members has a radial bore, and the other of said first and second members has a corresponding recess, so that when the screw threads of the first and second members engage, the radial bore may be aligned angularly with the recess. A resilient pin assembly is provided having pins located in said radial bore. The pins are thus resiliently urged in said radial bore toward said recess, so that when the radial bore is aligned angularly with the recess, the pins engage the recess, preventing further relative rotation between the first and second members.
