Abstract
A heavy-duty shackle has a shackle body with two opposing end sections, each of which having a through-opening for receiving a bolt, which has a threaded section for a locknut at one end and a head at the other end, the head outer edge being non-circular. The through-openings are each surrounded by at least one nut bearing face, which is raised relative to a bearing face, directly surrounding the through-openings, for the head. An anti-rotation means for the bolt is formed in each case by a recessed head receptacle in the nut bearing face, the head outer edge being accommodated fully in the recess and being interlockingly held in place therein.
