3/4-10 x 2 3/4 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. 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. External wrench access is useful when an internal socket recess would be hard to keep clear.
