ABSTRACT:
A manually manipulatable nut and bolt fastener for a battery terminal clamp provides an nut configured to engage one of the fingers of a typical bifurcated battery terminal clamp and a bolt engaging the other finger to move the fingers relatively responsive to nut-bolt motion. The nut-bolt combination is formed of flexibly resilient polymeric material to deform to accommodate axial and lateral repositioning and alignment of the bolt as the battery clamp fingers move relatively to each other. The fastener eliminates normal corrosion associated with metallic fasteners for battery terminal clamps.
