DIAMETER: Available in diameters from 3/16” through 1”.

LENGTH: Available in required lengths above the recommended standard minimums (L). Length is before weld. Stud diameters 1/2” and smaller will be approximately 1/8” shorter after welding. Diameters of 5/8” and larger will be approximately 3/16” shorter after welding.

MILD STEEL: Low carbon steel.

  • Mechanical Properties (as cold drawn):
  • Tensile: 55,000 psi min.
  • Reduction in Area: 50% min.

STAINLESS STEEL: Type 304 is the most commonly used. Other grades of stainless steel (except Type 303) are available when required.

THREAD: Standard thread is UNC2A. Maximum standard thread length is 3-7/8”.

FERRULES: All orders for studs include required ferrules.

PLATING: Plated studs are available in cadmium, zinc, and nickel, ASTM specifications A165 Type TS, A164 Type RS, and B-456. The welding end of the stud is not plated to prevent weld contamination. Information on other plating materials are available upon request.

ANNEALING: Stud ductility can be increased by 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.
