PREVAILING TORQUE FASTENERS

Prevailing torque fasteners create a thread interface between the fastener and the fastener counterpart in order to prevent the fastener from loosening.

ALL METAL PREVAILING TORQUE FASTENERS

These fasteners accomplish the thread interface by a designed distortion or deformation in the fastener.

NYLON INTERFACE PREVAILING TORQUE FASTENERS

These fasteners accomplish the thread interface by the presence of a nylon material on the fastener threads.

ADHESIVE COATED FASTENERS

These fasteners accomplish the thread interface by the presence of a thread-locking compound on the fastener threads. Refer to the appropriate repair
procedure in order to determine if the fastener may be reused and the applicable thread-locking compound to apply to the fastener.

A prevailing torque fastener may be reused ONLY if:
-

The fastener and the fastener counterpart are clean and not damaged

-

There is no rust on the fastener

-

The fastener develops the specified minimum torque against its counterpart prior to the fastener seating
