Manufacturing Data

Threads - Standard threads are UNC-2A for male threads, UNC-2B for female. Some sizes are also stocked in UNF-2A and 2B sizes. Other thread classifications are available on special order. Whenever possible, all studs are thread rolled.

Plating - Zinc plating is available according to ASTM-A 164-55 RS. Other plating materials available on request. Plating is removed from the weld base to prevent contamination on all studs except 10 gauge pins.

Annealing - Sunbelt arc welding studs can be annealed to a maximum of 75 Rockwell B for low carbon steel; 90 Rockwell B for stainless steel.

Flux - Except for some studs less than 5/16" diameter, all studs are solid fluxed at the center of the weld base.

Ferrules - All orders include ferrules when required. Ferrules are supplied with the studs and are not sold individually.


Disclaimer

The provided performance data is intended as guideline for specifications and strengths only and is based on assumptions of general and reasonable use. Performance suitability for any specific application should be determined by the user.
