Pre load and clamp load?

01/16/2008 11:46 AM

What is the difference between pre load and clamp load when referring to tighten fasteners? Are they different terms or one in the same?

The pre-load is what one gets when the bolt was tightened. At this moment the clamp force is equal to the pre-load. If after a time for instance a relaxation occurs the clamping force decreases and is not any more equal to the pre-load.

I hope this will make clear both notions.

If any other question please ask.
