1/2-13 x 1 3/4 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. Use the size to match the thread and length, then call out Half Dog, Full Dog, Cone, Oval, or Flat as the required point. External wrench access is useful when an internal socket recess would be hard to keep clear.

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. Flat points bear against a machined flat without intentional penetration into the mating surface.
