Abstract
An encapsulated metal bolt comprises a head portion having an encapsulating cap thereon with a plurality of conductive fibers therein electrically isolated from the head but electrically exposed to the surface of a complementary aperture.
Claims1
An encapsulated fastener for introduction through an aperture in a workpiece having conductive fibers therein, said fastener comprising a metal bolt having a head portion at one end, a threaded portion at the other end, and a shank between said head and end portions, and a plastic cap encapsulating the head portion of said bolt having a plurality of resin encapsulated electrically conductive fibers therein, said electrically conductive fibers being substantially electrically isolated from said metal bolt by the plastic resin of said cap, the radially outer periphery of said plastic cap being abraided to enhance electrical connection between the conductive fibers thereof and the conductive fibers of said workpiece intersecting the periphery of the aperture in said workpiece whereby electrical continuity is provided by the cap on said bolt across the aperture in said workpiece.
