Proto J5423MH Hand Socket 23mm 6-point 1/2 Drive

Product Description

The PROTO J5423MH is a 23 mm, 6-point hand socket built for professional mechanical and industrial use. Machined from alloy steel with a chrome-plated finish, it fits a 1/2 inch drive ratchet or breaker bar. The 6-point design delivers full contact on each flat of the fastener, reducing the risk of rounding. At a standard length of 1.53 inches overall, it is sized for general-purpose fastener work. This socket meets ASME B107.5 standards, making it appropriate for professional shops, fleet maintenance, and field service applications.

The J5423MH is suited for use on 23 mm hex fasteners in automotive, heavy equipment, and industrial maintenance settings. Standard length makes it a go-to choice when clearance allows direct access to the fastener. Licensed mechanics, fleet technicians, and maintenance professionals will find it at home in any 1/2 inch drive set. It handles both hand-torque and impact-adjacent breaker-bar applications in day-to-day service work.

Installation Notes

Ensure the drive tool is fully seated before applying torque to prevent socket or fastener damage. Power down or de-energize any equipment before accessing fasteners on electrical or mechanical assemblies. This socket is not tether capable and should not be used in elevated or overhead work environments where drop hazards exist. Inspect the socket for cracks or wear before each use.
