A battery terminal bolt preferably having a head portion, a washer portion, a sealing portion and a threaded portion. The sealing portion is disposed between the washer portion and the threaded portion and is preferably in the form of a frustoconical shape that allows the bolt to be substantially sealed when placed in an insert mold. The battery terminal bolt's washer portion has a geometry that substantially reduces abusive field torque failures and also provides increased pull-out strength. In a preferred embodiment, the washer portion contains semi-circular projections in a radial pattern around longitudinal axis of the battery terminal bolt.

Battery terminal bolt

A shippable in-assembly bolt having a head portion, a threaded portion containing threads and a gripper portion, wherein the gripper portion preferably comprises a grooved structure and an o-ring. The o-ring is intended to sit between the inner wall of a clearance hole in an assembly/subassembly and the grooved structure of the gripper portion. When the o-ring is in position between the inner wall of the clearance hole and the grooved structure of the gripper portion, the o-ring is in both compression and tension and acts to retain the bolt in the assembly during shipping operations. The invention can be used with any type of mechanical fastener, such as bolts, screws, pins, rivets, etc.
