Caution: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application.

These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
