3/8-16 x 5/8 is intended for mechanical fastening positions where the square head remains exposed and a selected point style contacts the mating part.

Typical applications include gear and sprocket locking where a selected point bears on a prepared shaft feature. The product record carries the size; the requested point is selected from the Half Dog, Full Dog, Cone, Oval, and Flat menu. 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.
