Tapped Studs are used in all types of applications. They can be welded to a flat surface, or to the inside or outside of an angle.


Arc stud welding is a process by which a metal fastener is welded to a parent metal through a fusion weld. Using a “ferrule” to capture and retain the weld’s heat, the molten metal created by the process cools and the weld site and produces a weld that is stronger than the stud itself. Drawn arc stud welding can weld dissimilar metals such as mild and stainless steel, as well as aluminum.

Our Tapped studs are composed of low-carbon steel. All purchases of Tapped studs come with the necessary ferrules required for welding, so you do not have to worry about making sure you have the necessary parts!

How to Order:
Specify base diameter, finished length before weld (BW) length, tap size, tap depth and type of material.
Ex: 5/8 x 1-1/4” (BW) Tapped Stud (TS) with a 3/8-16 x 7/16 tap, mild steel

When ordering Stainless Steel, SS will be added to the part number.

How to determine Before Weld (BW) Length

First establish the standing length of the stud after weld (AW).

Based on the diameter of the stud, include the following additional length before weld (BW).

Diameters up through 9/16″ add 1/8″ (will be 1/8” shorter AFTER weld)
Diameters from 5/8″ through 7/8″ add 3/16″ (will be 3/16” shorter AFTER weld)
Diameters 1″ through 1 1/4″ add 1/4″ (will be 1/4” shorter AFTER weld)
