Torque Control Best Practices for Thread-Locking Fasteners & Security Patches

Thread-locking fasteners and security patches help improve joint reliability by preventing fasteners from loosening due to vibration, thermal cycling, and dynamic loads. However, these locking features also add friction during installation, making it harder to achieve accurate, repeatable torque. Fasteners with pre-applied thread lockers or security patches require additional torque to overcome the friction created…
