Arc Studs

Arc Weld Studs

Arc weld studs (or Drawn arc studs) typically utilize a stud and an aluminum flux ball using a constant DC power supply to efficiently attach fasteners to a carbon steel or stainless-steel shell.  We can customize our studs to suit your application and are available in many different grades of steel including stainless steel and mild steel.

  • PD STUDS have a pitch diameter weld base (C). They are available in diameters 1/4" through 1". All orders for studs include required ferrules.
  • LENGTH Available in required lengths above recommended standard minimums (L). Length is before weld. Stud diameters 1/2" and below will be approximately 1/8" shorter after welding. 5/8" and above will be approximately 3/16" shorter after welding.
  • THREAD Standard thread is UNC2A. Maximum standard thread length is 3 1/2".
  • MATERIAL: Low Carbon Steel
  • Stainless Steel: Studs are also available in weldable stainless steel. Type 304 is the most commonly used. Other grades of stainless steel available when required.
  • ANNEALING: Stud ductility can be increased be annealing to 75 Rockwell B for low carbon steel and 90 Rockwell B for stainless steel.
  • FLUX: Studs 1/4" and over are solid fluxed.

FT Studs are available in diameters 1/4" through 1".
