Proto J5425M Hand Socket 25 Mm 12-point 1/2 Drive

Product Description

The PROTO J5425M is a 25 mm, 12-point hand socket designed for professional-grade manual torque work. It features a 1/2 inch square drive and a standard-length profile, making it a direct fit for ratchets, breaker bars, and torque wrenches in the same drive class. The chrome-plated finish resists corrosion and provides surface durability for repeated tool-room and field use. This socket is built for licensed tradespeople and experienced mechanics who require a reliable 25 mm hex fastener solution in heavy-duty service applications.

This socket is suited for mechanical, HVAC, plumbing, and electrical installation work where 25 mm fasteners are encountered on equipment panels, flanges, pump assemblies, motor mounts, and similar hardware. Standard-length geometry allows use in open access areas where deep-reach or low-profile sockets are not required. Trades carrying a 1/2 inch drive set will find this socket integrates directly into their existing ratchet and extension inventory.

Key Features

• 25 mm socket size for metric fastener applications
• 12-point design engages fastener heads at multiple positions, reducing slippage risk
• 1/2 inch square drive compatible with standard ratchets, extensions, and torque wrenches

Compatibility

Installation Notes

Install and remove using a 1/2 inch drive ratchet, breaker bar, or torque wrench. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding fastener corners. Do not use impact drivers with this hand socket unless the product is specifically impact-rated. Inspect the socket for cracks or wear before each use and remove from service if damage is found.
