7/16-14 x 1 1/4 is a low carbon steel, case hardened square head set screw for wrench-driven holding where an external square head is acceptable.

Typical applications include mill and conveyor drives where square-head hardware remains accessible during service. The row represents a square-head size, while the point selection is made from Half Dog, Full Dog, Cone, Oval, and Flat. 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.
