7/16-14 x 1 1/2 gives maintenance teams a classic square-head set screw with a full UNC callout and a wrench-driven head for heavy mechanical layouts.
Typical applications include pulleys and sheaves on line shafts where the head is intentionally exposed. Use the size to match the thread and length, then call out Half Dog, Full Dog, Cone, Oval, or Flat as the required point. Half Dog points register into shallow holes or slots when location matters under load.
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 set screws are the related screwdriver-driven option when flush-fitting access is preferred.
