Proto J5273AM Hand Socket 10 Mm 12-point 3/8 Drive

Product Description

The PROTO J5273AM is a 10 mm, 12-point hand socket designed for general-purpose fastener work in mechanical, industrial, and trade service environments. Built from alloy steel with a chrome-plated finish, it fits a 3/8 inch drive and measures 1.75 inches in overall length. The 12-point design allows engagement at 30-degree intervals, giving techs more handle positions in tight clearances. This socket is a standard item for HVAC, plumbing, and general mechanical service where metric fasteners are common. It meets ASME B107.5M standards, confirming dimensional and performance conformance for professional use.

This socket suits residential and commercial service applications involving metric hardware. Its compact 1.75-inch length fits into confined spaces common in equipment panels, valve assemblies, and mechanical enclosures. Licensed technicians and journeymen across HVAC, plumbing, electrical, and general mechanical trades will find it a reliable addition to a 3/8 inch drive set. Sold individually, it works as a direct replacement or addition to an existing socket set.
