1/4-20 x 1 3/4 is intended for mechanical fastening positions where the square head remains exposed and a selected point style contacts the mating part.

Typical applications include gear and sprocket locking where a selected point bears on a prepared shaft feature. Because point style changes the mating contact, buyers should specify Half Dog, Full Dog, Cone, Oval, or Flat with the size. External wrench access is useful when an internal socket recess would be hard to keep clear.

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.
