3/4-10 x 1/2 is a square head set screw used where an open wrench or socket can access the head and point style must be specified at order.
Typical applications include couplings and collars in heavy service where point style is part of the assembly design. Use the size to match the thread and length, then call out Half Dog, Full Dog, Cone, Oval, or Flat as the required point. 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 set screws are the related screwdriver-driven option when flush-fitting access is preferred.
