Tapped Internally Threaded Reduced Base Arc Weld Stud
Tapped Internally Threaded Reduced Base

Tapped Internally Threaded Reduced Base Arc Weld Studs are available in mild steel and stainless steel materials. As the majority of these studs are made to each customer’s order, the customer can specify all dimensions.

Coarse and fine threads are available in both imperial (UNC-2B and UNF-2B) and ISO metric (Class 6g) sizes. The imperial coarse threads are depicted below (UNC-2B).

Internally Threaded Tapped weld studs are used to secure components to larger structures and or as a standoff. The reduced weld base diameter may satisfy application needs and or equipment limitations.
