REDUCED BASED STUDS: The studs have a reduced weld base (C).
DIAMETER: Available in diameters from 1/4” 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.
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.
