Abstract

A Locking bolt according to the invention comprises a tubular bolt member (1) and an expansion bolt (2). The tubular member (1) consists of an externally screw-threaded shaft (3) terminating in a bolt head (5). The shaft (3) and head (5) are formed with an axial hole (6) at least a part of which is internally screw-threaded at (10). The expansion bolt (2) engages that screw-thread for advancement of the expansion bolt (2) axially along the axial hole (6). This advancement causes the radial expansion of a segmented portion (9) of the screw-threaded shaft (3), to press its screw-threads radially outwardly against the internal screw-threads of the nut or threaded bore (15) in which the bolt is received, to lock the bolt in the nut or threaded bore (15). The locking bolt of the invention removes the need for a locking nut on an axially projecting end portion of the bolt.
