SHOULDER STUDS: Threaded studs with a weld base diameter greater than the thread diameter.
DIAMETER: Available in diameters from 1/4" through 3/4", in thread diameters to maximum (C).
LENGTH: Available in required lengths above the recommended standard minimums (L). The minimum overall length is determined by a combination of L and the required A. The 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.
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.
