Proto J5423M 23mm 12-point 1/2 in Drive Hand Socket

Product Description

The PROTO J5423M is a 23 mm, 12-point hand socket designed for use with a 1/2 inch drive ratchet or breaker bar. Built to standard length, it features a chrome-plated finish that resists corrosion and makes cleanup easier after use in greasy or dirty environments. This socket is suited for professional mechanics, maintenance technicians, and trade professionals working on heavy equipment, automotive systems, or industrial machinery where a 23 mm fastener size is common. At 0.25 pounds, it is lightweight enough for extended use without added fatigue.

This socket fits standard 1/2 inch drive tool setups, making it compatible with the ratchets, extensions, and torque wrenches already in most professional toolkits. The 12-point design allows engagement at 30-degree increments, which is useful when working in tight spaces with limited swing arc. It is well suited for automotive repair shops, fleet maintenance bays, construction sites, and general industrial maintenance applications where metric fasteners are regularly encountered.

Key Features

• 23 mm socket size for metric fastener applications
• 12-point design allows positioning at 30-degree intervals for confined-space use
• 1/2 inch drive compatible with standard ratchets, extensions, and torque wrenches
• Standard length profile suitable for most general-purpose fastener access
• Chrome-plated finish for corrosion resistance and easy cleaning

Compatibility

Designed for use with standard 1/2 inch drive hand tools including ratchets, breaker bars, and torque wrenches. Fits any 1/2 inch drive tool setup accepting standard-length sockets.

Installation Notes

This socket is installed and removed by hand tool professionals and general mechanics using standard 1/2 inch drive equipment. Ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Inspect the socket and drive square for wear or damage before use on high-torque fasteners. Store in a dry location to preserve the chrome-plated finish.
