FASTENER FOR FIBERGLASS AND OTHER COMPOSITE STRUCTURES

摘要

A threaded fasteners combines two or more of (a) a self-drilling tip that is long enough and/or sufficiently distanced from the threads to assure that drilling action is complete before the first thread engages the surface of the work piece, (b) high-low threads, and (c) a factory pre-applied adhesive/sealant. Such fasteners are especially advantageous in applications where connections to fiberglass are needed, and especially in applications such as boats or other transportation vehicles where leaks resulting from drilled cavities are problematic.
