“When you torque the nut, it is actually telling you how much stress and stretch you have applied to the stud, which, of course, equals clamp load. But, a 1-inch air gun can easily produce [more ...

Excessive torque applied by large pneumatic impact wrenches can stretch the studs, dramatically reducing their ability to maintain adequate clamping force. Tighter is not better, especially when ...

And thirdly, normal torque measurement procedures do not produce accurate tension/clamping force measurements at extreme temperatures as compared with normal ambient conditions. So even though you ...

Or the transmission, which aside from a new torque converter, ... and weaken. If the bolt weakens, it may have less clamping force than stock, or in a worst case scenario, break.

Proper Fastener Selection and Application are Key to Bolted Joints That Won’t Loosen or Lose Clamping Force. ... bolts can be untightened with nearly the same force as the original preload torque.
