SELF-SEALING THREADED FASTENER AND PROCESS FOR MAKING THE SAME

摘要

An integral sealing element is bonded directly to the engaging surface and selected threads of a threaded fastener. The sealant is a soft pliable olefin or polyolefin based material and is designed to flow between the engaging surface of the fastener and the abutting bearing surface of a receptacle as the fastener is threadably tightened into the receptacle for creating a tight seal between the threaded fastener and the receptacle.
