3/8-16 x 5 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. Point choice is part of the order detail, with Half Dog, Full Dog, Cone, Oval, and Flat handled under this family. Half Dog points register into shallow holes or slots when location matters under load.

Cold Headers keeps the record focused on usable engineering details so buyers can compare the callout against drawings and service notes. 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.
