Proto J5023M Deep Hand Socket 23mm 12-point 3/8 Drive

Product Description

The PROTO J5023M is a deep hand socket designed for professional hand-tool use in mechanical, industrial, and maintenance applications. It features a 23 mm socket size with a 12-point geometry, allowing engagement from multiple positions on hex and standard fasteners. The 3/8 inch drive fits standard ratchets and drive tools common in trade toolkits. Constructed from alloy steel with a chrome-plated finish, it is built for durability and corrosion resistance. At 2.75 inches in overall length, the deep profile provides the clearance needed to reach recessed fasteners and extended bolt threads that standard-depth sockets cannot access.

This socket suits automotive technicians, maintenance mechanics, pipefitters, and industrial service professionals working on equipment where fasteners sit deep within a housing, frame, or recess. The 12-point design works on both standard hex fasteners and double-hex fasteners, giving broader utility across mixed-hardware environments. It is appropriate for residential, commercial, and industrial service work wherever a 3/8 inch drive set is in use.

Key Features

• 23 mm socket size fits common metric fasteners found in automotive and industrial equipment
• 12-point geometry allows engagement at multiple rotational positions, useful in tight quarters
• Deep profile at 2.75 inches overall length reaches recessed bolts and extended studs
• 3/8 inch drive fits standard ratchets, extensions, and torque wrenches
• Alloy steel construction with chrome-plated finish for strength and corrosion resistance
• Meets ASME B107.5 standards for hand socket tools

Compatibility

Designed as an OEM-style hand socket compatible with standard 3/8 inch drive ratchets, extensions, and torque wrenches using a 23 mm metric fastener application.

Installation Notes

Install and remove using a compatible 3/8 inch drive ratchet or torque wrench. Ensure the fastener and socket are fully seated before applying torque to avoid rounding the fastener head. De-energize or depressurize any system before working on fasteners in live mechanical assemblies. Do not use impact drivers with this hand socket unless the tool is specifically rated for impact use.
