All of the door hardware production attaching screws contain
an epoxy thread-locking compound in order to ensure that the minimum original
torque setting is maintained. The service attaching screws may not contain
a thread-locking compound. Treat the threads of the fasteners using LOCTITE® 75
GM P/N 1052279 or the equivalent, for the following reasons:
| • | In order to prevent loosening of the service screws |
| • | In order to renew the thread-locking characteristics of production
screws |
LOCTITE® 75 GM P/N 1052279 is a two-part material
that is applied to the hardware as a liquid. After installation and tightening,
the adhesive cures in order to perform the following functions:
| • | Prevent loosening of the screws |
| • | Prevent backing out of the screws |
The adhesive bond does not prevent future removal. You may use LOCTITE® 75
GM P/N 1052279 or the equivalent on any threaded fastener.
