Prevailing Torque*

Prevailing torque is a critical characteristic of certain types of fasteners designed to resist loosening under dynamic conditions. By understanding the mechanisms that provide prevailing torque and the methods for measuring it, engineers can select and apply these fasteners to enhance the reliability and safety of assemblies in various applications.

Industry Applications of Prevailing Torque Fasteners

Automotive Industry:

• Used in engine assemblies, suspension systems, and other critical components where vibration and dynamic loads are common.

Oil & Gas Industry:

• Essential for ensuring the integrity of fasteners in oil & gas sector where extreme vibration and temperature changes occur.

Machinery and Equipment:

• Applied in industrial machinery, construction equipment, and other applications where fasteners are subjected to repetitive motion and vibration.

Electronics:

• Used in securing components that may be subjected to thermal cycling or mechanical movement.

Standards for Prevailing torque

• BS 4929 Part 1 (as specified by defence standards NES / DEF Stan)
