Hardware Attachement Thread Locking
HARDWARE ATTACHMENT THREAD LOCKINGAll door hardware production attaching screws contain an epoxy thread-locking compound to insure that the minimum original torque setting will be maintained. Service 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 Part 1052279, Loctite 75 or equivalent which is a two-part material applied to the hardware attachment as a liquid. Upon installation and tightening, the adhesive cures to bond the attachment and prevent loosening or backing out. The adhesive bond does not prevent future removal. Loctite 75 or equivalent can be used on any threaded fastener.
