General Information

Description:
Studs are designed to account for length adjustments during the welding process:

  • Imperial Studs:

    • Up to 1/2" diameter: Reduced by 1/8" after welding.
    • 5/8" diameter and above: Reduced by 3/16" after welding.

Note: All metric ARC studs are listed by their length after welding (LAW).

Special Orders: Other diameters, lengths, and materials are available by special order (minimum quantities may apply).
