DEFINITION

Classification: 411/133

Member fixed to bolt shank, and member or bolt fixed to substructure:

(under subclass 132) Device wherein one or both of the member and the bolt are either limited in, or fixed against, turning relative to the substructure, and wherein means is provided, at least on the member, but, more commonly, on both the member and the shank of the bolt, whereby the two engage each other in such a manner that the turning of one relative to the other, at least in one direction, is either eliminated or severely limited.

(1) Note. The member is sometimes a composite of two or more coacting elements, one of which elements engages the substructure and the other of which engages the shank of the bolt.

(2) Note. The limiting or fixing of the member may involve, for example, substructure-penetrating formations on the member, while the limiting or fixing of the bolt may be predicated upon, for example, the squaring of a portion of the shank for engaging an opening complementary thereto in the substructure.

(3) Note. The means on the shank of the bolt may comprise structure in the nature of a flat, a keyway, a thread, etc.
