1-8 x 1 1/2 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. 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.
