Proto J5274AM Hand Socket 11mm 12-point 3/8 Drive

Product Description

The PROTO J5274AM is an 11 mm, 12-point hand socket designed for use with a 3/8 inch drive ratchet or breaker bar. Manufactured from alloy steel with a chrome-plated finish, it delivers the corrosion resistance and surface hardness that trade professionals demand in a shop or field environment. At 1.75 inches overall length, it fits in tight spaces without sacrificing strength. The 12-point geometry allows six times the engagement positions of a standard 6-point socket, making it faster to seat on fasteners in confined areas. It meets ASME B107.5M standards for hand socket dimensional and performance requirements.

This socket is suited for automotive, mechanical, and industrial maintenance applications where 11 mm fasteners are common. Typical install scenarios include engine bay work, equipment assembly, and general mechanical repair. It is compatible with standard 3/8 inch drive hand tools including ratchets, extensions, and torque wrenches. The chrome finish makes it easy to wipe clean after use and resistant to surface rust in moderate shop conditions.

Installation Notes

This socket is installed and removed by hand tool technicians in automotive, industrial, and general mechanical service settings. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding the fastener head. Do not use hand sockets with impact drivers or impact wrenches unless the socket is impact-rated. Inspect for cracks or chips before each use and remove from service if damaged.
