37 General Torque Recommendations Listed here are the general torque recommendations for most ARP fasteners. Recommended torque is equal 75% of the fastener’s yield strength. Simply read down to the correct fastener size, then across to find the torque value for your application. ALWAYS LUBRICATE THE FASTENERS PRIOR TO APPLYING TORQUE TO ENSURE ACCURATE READINGS. Note 1. The torque values represented here are intended for general information only and bulk fasteners, not for specific installations. Note 2. On specific installations, where the supplied instructions deviate from the torque values listed here, always follow the specific instructions packaged with each kit. Recommended Torque to Achieve Optimum Clamp Load Using ARP Ultra-Torque Fastener Assembly Lubricant Note: For those using Newton-meters as a torquing reference, you must multiply the appropriate ft.-lbs. factor by 1.356.
