ABSTRACT:
Locking bolt assembly comprises a bush (9) fixed in use with respect to a structure to which a bolt of the assembly is to be engaged and a socket (1) carried on the bush (9) and provided with locking means (6) for preventing rotation of the socket (1) on the bush (9) but permitting limited longitudinal movement thereon. The bolt is threaded and has a head (3) dimensioned for rotational locking engagement within socket (1). A coil spring (7) urges the head (3) and socket (1) into rotational locking engagement. In use the socket (1) may be moved longitudinally with respect to said bush (9) against the action of the spring (7) from a position in which the head (3) and the socket (1) are radically locked, to a position in which the head (3) is freed for rotation and engagement with a co-operating nut fixed to the structure.
