5/16-18 x 2 is a square head machine set screw for assemblies that need point-style selection and direct wrench access.

Typical applications include retrofit work where the mating hole, flat, or seat determines the point style. Because point style changes the mating contact, buyers should specify Half Dog, Full Dog, Cone, Oval, or Flat with the size. Half Dog points register into shallow holes or slots when location matters under load.

Since 1962, Cold Headers has helped industrial buyers identify specialty set screws by thread, length, head style, and point requirement. 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.
