When a threaded component must be seated with external wrench access, 1/2-13 x 2 provides the traditional square head set screw format.

Typical applications include construction machinery where large wrench flats are easier to clean and grip. Point choice is part of the order detail, with Half Dog, Full Dog, Cone, Oval, and Flat handled under this family. Flat points bear against a machined flat without intentional penetration into the mating surface.

Cold Headers supports square-head set screw sourcing with a catalog organized around exact size, standard, and point selection. The family runs UNC coarse thread throughout, the traditional square-head series. For cup point square heads, use the separate Cup Point Square Head Set Screws category rather than this five-point family.
