1/2-13 x 3/4 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. Because point style changes the mating contact, buyers should specify Half Dog, Full Dog, Cone, Oval, or Flat with the size. Point selection should reflect the shaft feature, acceptable marking, and expected service adjustment.

Since 1962, Cold Headers has helped industrial buyers identify specialty set screws by thread, length, head style, and point requirement. Review the selected point, wrench clearance, and mating feature before substitution. Oval points suit grooves or repeated adjustment where a radiused contact is useful.
