Proto J5425MN 25mm 12-point 1/2 Drive Hand Socket

Product Description

The PROTO J5425MN is a 25 mm, 12-point hand socket designed for 1/2 inch drive ratchets, breaker bars, and torque wrenches. Built from steel with a chrome-plated finish, this standard-length socket measures approximately 1-59/64 inches overall. The 12-point design engages fastener flats at multiple positions, reducing the arc needed to reposition the tool in tight quarters. It meets AS4984A, ASME B107.110-2012, and SAE AS955 standards, making it suitable for professional and industrial use. Licensed trades, fleet mechanics, and service technicians working on metric fasteners will find this socket a reliable addition to a 1/2 inch drive set.

This socket is intended for hand-tool use with standard 1/2 inch drive equipment. It is well suited for automotive, industrial maintenance, and mechanical assembly applications where a 25 mm metric fastener is encountered. The standard-length profile fits most accessible fastener locations without the bulk of a deep socket. The chrome finish resists corrosion and simplifies cleanup in shop environments. This socket is not tether capable and is packaged individually.

Installation Notes

Install and remove this socket using hand tools only — it is not rated for impact driver use. Ensure the drive tang is fully seated and the detent ball is engaged before applying torque. Inspect the socket for cracks or deformation before each use, and remove from service if any damage is found. Store in a dry location to preserve the chrome finish.
