Title: MULTI-PATCH THREADED FASTENER
Abstract:
A multi-patch threaded fastener includes a shank having a threaded portion and two or more polymer patches disposed on the shank. The two or more polymer patches are configured to wedge against a mating threaded component to promote contact between non-patched threaded portions of the shank and the mating threaded component to resist removal from the mating threaded component. A method of making the multi-patch threaded fastener includes positioning two or more nozzles for dispensing a patch material at locations corresponding to desired patch locations on the shank, conveying the shank past two or more nozzles, and dispensing the patch material from each nozzle onto the shank to form the two or more polymer patches on the shank.
