Studs vs. Bolts

When you torque a stud with two nuts, torsional movement will take place at either end of the nut-stud-nut assembly, creating a much better retention of clamping force throughout the fastener. When you tension, it really doesn't matter, you are lifting the nut, stretching the shank against the underface of the head, and then running the nut down to capture preload. Get price

Welding Secures America's Infrastructure

2016/4/26Stud welding, a method that applies a metal fastener to one side of a substrate metal, is frequently used in projects that require an aesthetically clean appearance on the face of one of the pieces.
