5/8-11 x 5 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. Specify the point style at order; the same size can be supplied as Half Dog, Full Dog, Cone, Oval, or Flat. Flat points bear against a machined flat without intentional penetration into the mating surface.

Cold Headers can review less-common square-head sizes, long lengths, and point combinations when the standard catalog matrix does not cover the need. The family runs UNC coarse thread throughout, the traditional square-head series. Full Dog points register into mating holes or slots when the design calls for deeper engagement.
