1/2-13 x 1 is built for legacy machinery and industrial assemblies that still specify a square head set screw instead of a headless socket screw.
Typical applications include large adjustment stops, travel-limit hardware, and machine fixtures. This family is ordered as one size across five point choices: Half Dog, Full Dog, Cone, Oval, and Flat. Flat points bear against a machined flat without intentional penetration into the mating surface.
Cold Headers keeps this legacy set screw family practical for maintenance, repair, and production users who still need the square-head form. The family runs UNC coarse thread throughout, the traditional square-head series. 316 stainless square-head versions can be reviewed as non-catalog quote requests when the application requires that material.
