RB weld studs are available in mild steel and stainless steel materials. RB studs are most often made to each customer’s order.

RB studs have a smaller weld base diameter than TP, TF and TFB studs and thus produce a smaller flash diameter. RB studs permit smaller clearance holes in your design. The load strengths for RB studs are determined by the weld base diameter.
