1-8 x 2 1/4 supports machine service where a protruding square head is intentional because it is easy to grip, inspect, and remove.

Typical applications include drive components, jackshaft assemblies, and plant maintenance repairs. Specify the point style at order; the same size can be supplied as Half Dog, Full Dog, Cone, Oval, or Flat. 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. Half Dog points register into shallow holes or slots when location matters under load.
