For replacement work on older equipment, 5/8-11 x 1 3/4 keeps the UNC pitch patch, length, and square-head drive clear in the product record.
Typical applications include farm implements, mill equipment, and production machinery that need wrench clearance. The row represents a square-head size, while the point selection is made from 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. Cup Point Slotted Headless Set Screws are the related headless option when flush-fitting screwdriver access is preferred.
