• ### What is Proof Load of a Bolt and How is it Different from

Proof load is the limit of the elastic range of the bolt. Designing for the use of bolts according to proof load can help prevent plastic deformation. As long as a bolt is never tensioned beyond its specified proof load you can be assured that it has maintained its original size and shape and may be safely reused. Tension vs. Stretch
