Weld Stud

A weld stud is a threaded fastener that is welded to a metal part. It gives a permanent male thread for holding another component.

A weld stud joins to a metal part by drawn arc or stud welding. It takes a nut or a threaded part of the same thread and class. A fully threaded stud allows a nut to sit at any point along its length.

Weld studs are often made in mild steel, stainless steel or aluminium. The material must match the base metal for a sound weld.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance with the material and thread size. On receipt, check the thread is clean and the weld end is free from rust or oil.
