Some production door hardware attaching screws contain an epoxy thread-locking compound to ensure that the original torque setting will be maintained.
Service (replacement parts) attaching screws may not contain a thread-locking compound. To prevent loosening of service screws or to renew thread-locking characteristics of production screws, the threads of the fastener(s) can be treated with GM #12345382 Adhesive/Sealant Compound, or equivalent. Upon installation and drying, the adhesive cures to bond the attachment and to prevent it from backing out. The adhesive bond does not prevent future attachment removal, if required. Adhesive/Sealant Compound or equivalent can be used on any threaded fastener.
