Proto J5409MH 9mm 6-point 1/2 in Drive Hand Socket

Product Description

The PROTO J5409MH is a 9 mm, 6-point hand socket designed for 1/2 inch drive ratchets and extensions. Built from alloy steel with a chrome-plated finish, it delivers solid corrosion resistance and a clean grip surface for repeated use in professional shop and field environments. The 6-point design applies torque to the flat sides of a fastener, reducing the risk of rounding under load. Overall length is 19/32 inches in a standard-length profile. Licensed mechanics, maintenance technicians, and industrial tradespeople working with metric fasteners will find this socket a direct-fit addition to a 1/2 inch drive set.

The J5409MH suits general mechanical and maintenance applications where 9 mm metric fasteners are encountered. Common install scenarios include automotive service, HVAC equipment panels, pump and motor assemblies, and light industrial maintenance. It is a single-piece, non-tethered socket intended for standard bench, bay, or field service work. It meets ASME B107.5M standards, confirming dimensional and performance compliance for hand socket tooling.

Key Features

Compatibility

Designed for use with 1/2 inch drive ratchets, breaker bars, extensions, and torque wrenches. Fits any standard 1/2 inch square drive tool accepting metric hand sockets.

Installation Notes

This socket is intended for installation and removal of 9 mm metric fasteners using 1/2 inch drive hand tools. Ensure the socket is fully seated on the fastener before applying torque to prevent slipping. Do not use hand sockets with impact drivers unless the socket is impact-rated. This socket is not tether-capable and should be secured by other means when working at elevation or in confined spaces per applicable safety protocols.
