Proto J5408M Hand Socket 8 Mm 12-point 1/2 in Drive

Product Description

The PROTO J5408M is an 8 mm, 12-point hand socket built for professional mechanical and maintenance work. It features a 1/2 inch drive and is manufactured from alloy steel with a chrome-plated finish for corrosion resistance and a clean appearance. The 12-point geometry allows engagement at 30-degree increments, giving technicians more wrench swing options in tight spaces. Overall length is 1-19/64 inches, placing it in the standard-length category. This socket is appropriate for use with any 1/2 inch drive ratchet, breaker bar, or torque wrench. It meets ANSI standard B107.5M and carries a limited lifetime warranty.

This socket is suited for automotive, HVAC equipment, and general mechanical service applications where 8 mm fasteners are common. Standard-length sockets like the J5408M are the go-to choice when clearance around the fastener is not a concern and a full-depth seating engagement is preferred. The chrome finish makes it easy to wipe clean in shop environments. It ships in a package quantity of one.
