Proto J5225M 25mm 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5225M is a 25 mm, 12-point hand socket built for professional-grade fastener work. It accepts a 3/8 inch drive and measures 1.375 inches in overall length, classifying it as a standard-length socket. The socket is machined from alloy steel and finished with a chrome plating that resists corrosion and simplifies cleanup in shop and field environments. It meets ASME B107.5 dimensional and performance standards. Mechanics, maintenance technicians, and industrial service professionals will find this socket suited to high-cycle fastener removal and installation where precise fit and durability are required.

This socket is used in automotive, industrial, and general mechanical service applications where 25 mm fasteners are encountered. The 12-point geometry engages hex fasteners from more clock positions than a 6-point socket, making it practical in confined spaces with limited swing. It is compatible with any standard 3/8 inch drive ratchet, breaker bar, or torque wrench. This socket is not tether capable and is sold individually.

Compatibility

Designed as an OEM-style replacement or direct-use socket compatible with any standard 3/8 inch drive tool system requiring a 25 mm, 12-point metric socket.

Installation Notes

Install and remove using a 3/8 inch drive ratchet, breaker bar, or torque wrench. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding. This socket is not rated for impact driver use. Inspect for cracks or wear before use in safety-critical applications.
