7/16-14 x 3 1/2 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. This family is ordered as one size across five point choices: Half Dog, Full Dog, Cone, Oval, and Flat. External wrench access is useful when an internal socket recess would be hard to keep clear.

Cold Headers brings long socket and set screw experience to older machine platforms where square-head hardware is still specified. Review the selected point, wrench clearance, and mating feature before substitution. Socket set screw families provide the internal-drive alternative where square-head projection or wrench swing will not clear.
