Abstract
A shear bolt assembly for a load limiting line support for a post insulator comprising a bolt having a first portion engaged with a saddle of the line support and a collar engaged by a line clamp. The collar is in abutting relation with the bolt and the collar and bolt have aligned axial bores in which a shear pin is secured. The shear pin can be secured in the collar and bolt by an adhesive layer and the shear pin can be brought into electrical contact with the bolt by providing a knurled section at one end which establishes interference fit and mechanical contact between the shear pin and the bolt.
