ABSTRACT:
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.
