Turn-of-Nut/Part Turn Method - Applied Bolting
Webfaces together. The rotation of a bolt (torque) at some point causes it to stretch (tension). Several factors affect how much tension occurs when a given amount of tightening torque is applied. The first factor is the bolt’s diameter. It takes more force to tighten a 3/4-10 bolt than to tighten a 3/8-16 bolt because it is larger in diameter. WebBolting torque to develop 50% Bolt Yield Stress at Nut Factor, K=0.16. This Table is applicable to Never-Seize paste and Fel-Pro lubricant, K=0.16.
