1/2-13 x 1 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. The row represents a square-head size, while the point selection is made from Half Dog, Full Dog, Cone, Oval, and Flat. Point selection should reflect the shaft feature, acceptable marking, and expected service adjustment.

Cold Headers keeps the record focused on usable engineering details so buyers can compare the callout against drawings and service notes. Review the selected point, wrench clearance, and mating feature before substitution. When the assembly cannot accept an exposed square head, compare headless socket set screw families before substituting.
