Frequently Asked Questions

Definition of weld screw: a screw that has a flat offset head and can be made captive by spot welding.

Although welding a bolt is not an ideal solution to many engineering issues, it may sometimes be necessary. … It should be noted that certain bolts’ grades and size can make it impossible or unsafe to weld them. Welding on a heat-treated bolt will weaken it because it would heat the bolt beyond its tempering point

 A weld nut is a special type of nut specifically designed to be welded to another object (spot welding).

Welding fasteners are used to create a super-strong and permanent connection between steel and the fastener. They are often chosen for their efficiency and ability to create unbreakable welds with the surface
