Abstract

A slack-resisting bolt comprises two parts 2, 3 which are separable at the clamping position of a nut 7. An internally threaded hole 4 is bored in the part 3 of the shank, and on externally threaded projection 5 is formed on the head part 2 and the projection 5 is screwed into the hole 4 so as to join the two shank parts together and form the complete shank. A screw driver slot or squared end portion 11 for rotating the part 3 is provided at the free end thereof. After the bolt is secured in position by the nut 7, the part 3 of the shank is turned in a direction so as to unscrew it from the body part 2 and thereby securely lock the nut 7 on the shank. The projection 5 may be formed in the separable part 3 and the bore 4 in the head part 2 (Figure 1 not shown). Two nuts may be used, the outer one being locked by the two-part shank.
