Material: Low carbon steel, ASTM A29, 1010 1020. NT studs are also available in weldable stainless steel

How to Order:
Specify diameter, thread size before weld (BW) length, type of material.
Ex: 1/2 x 1 No Thread Pin

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

How to determind 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)
