1/4-20 x 6 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. Because point style changes the mating contact, buyers should specify Half Dog, Full Dog, Cone, Oval, or Flat with the size. 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.
