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
