Locking screw arrangement for fastening machine parts together has sawtooth-shaped cutout in screw threads parallel to axis of screw and spring-loaded pawl in nut engages in cutout

摘要

The threads of a locking screw arrangement for fastening machine parts together have a sawtooth-shaped cutout (3). The cutout in the screw threads is parallel to the longitudinal axis of the screw. The nut (4) has a cutout in its female thread containing a spring-loaded pawl (5). The pawl in the nut engages in the cutout in the screw thread and is pushed toward the screw by a lump of resilient material (6).
