Abstract

Locking fastener comprising a threaded part such as a bolt or nut and a locking plate which fits over the bolt or nut and is prevented from rotation by engagement with a stationary object such as a protrusion on the part to be secured. The locking plate has an opening with a contour which mates with the outer contour of the fastener to prevent rotation of the fastener, and the plate is retained on the fastener by a retainer mounted in a groove formed in the fastener itself. The retainer is free to rotate in the groove and is free from stress due to vibration, heat or cold.
