3/8-16 x 2 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. Half Dog, Full Dog, Cone, Oval, and Flat points are the ordering paths for this square-head series. Point selection should reflect the shaft feature, acceptable marking, and expected service adjustment.
Cold Headers keeps this legacy set screw family practical for maintenance, repair, and production users who still need the square-head form. Review the selected point, wrench clearance, and mating feature before substitution. Cup Point Slotted Headless Set Screws are the related headless option when flush-fitting screwdriver access is preferred.
