Options To Consider When Choosing Threaded Weld Studs

There are many different options in weld studs that have a full thread or partial thread. In addition to the thread, it is important to consider where the weld studs are to be used and what types of issues may pose concerns. Choosing the right weld stud alloy is just as important as the choice of the weld stud itself.

Full Thread

When most people think of threaded weld studs, they are thinking of the fully threaded or full thread options. As the name implies, these studs are threaded from the top to very close to the bottom. The bottom part of the weld stud, which is designed to include the ignition tip and the very slight area of the unthreaded shaft, allows for full welding of the stud to the workpiece surface.

The benefit to these threaded weld studs is the ability to tighten up to the desired level for mating different thicknesses of materials to the base metal.

Pitch Diameter

Similar in appearance to the full thread, the pitch diameter types of weld stud have a more significant non-threaded area at the ignition tip end of the stud. Still considered threaded weld studs, these types of studs are ideal when strength in the weld stud is a priority for the job. The unthreaded area of the base is stronger and more durable than a similar area with threads, adding the additional strength.

Shoulder Base

The shoulder base weld studs have a significant solid component with a smaller diameter threaded area on the top of the weld stud. This is ideal for seating the part against the stud, creating a precise space while still using the strength of the welding process to hold the mated piece parallel to the base.

Choosing mild steel, stainless steel, aluminum or other custom selected alloys for both CD and drawn arc stud welds allows for the ideal shape, size, and properties for any job.
