It accepts a 3\/8 inch drive and is sized for 3\/8 inch hex spline fasteners with a 12-spline configuration. This socket is built for use with ratchets, torque wrenches, and impact-rated drive tools in mechanical, HVAC, plumbing, and electrical service environments. It meets Federal Specification GGG-W-641e and ANSI Spec B107.1, confirming dimensional and performance compliance for trade and government applications. Lightweight at 0.06 pounds, it suits toolbox carry without adding bulk.\u003c\/p\u003e\u003cp\u003eThis socket fits common service scenarios where spline-drive fasteners are encountered on equipment panels, mechanical assemblies, and structural hardware.
