Proto J5523M Hand Socket 23 Mm 12-point 3/4 Drive

Product Description

The PROTO J5523M is a 23 mm, 12-point hand socket designed for use with a 3/4-inch drive ratchet or breaker bar. Built from alloy steel with a chrome-plated finish, this standard-length socket measures 2 inches overall and is suited for heavy-duty fastener work in professional trade and industrial environments. The 12-point geometry allows engagement at 30-degree increments, providing more positioning options in confined spaces. It meets ASME B107.110-2012 standards, confirming dimensional and performance compliance for professional-grade hand tool applications.

This socket is used across mechanical, maintenance, and industrial service applications where 23 mm fasteners and a 3/4-inch drive are required. Common install scenarios include equipment assembly, heavy machinery maintenance, fleet service, and structural fastener work. Its standard length profile makes it suitable for general-purpose use where a deep or impact socket is not needed. Licensed mechanics, industrial maintenance techs, and pipefitters frequently reach for 3/4-drive sockets at this size range.

Key Features

• 23 mm socket size fits metric fasteners common in heavy equipment and industrial applications
• 12-point design allows engagement at 30-degree increments for better access in tight spaces
• 3/4-inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Alloy steel construction provides strength for high-torque applications
• Chrome-plated finish resists corrosion and aids cleaning
• Meets ASME B107.110-2012 for dimensional and performance compliance

Compatibility

Designed for use with 3/4-inch drive ratchets, breaker bars, and torque wrenches. Fits 23 mm hex fasteners in standard-clearance applications requiring a 12-point socket.

Installation Notes

Install and remove by a qualified mechanic or maintenance technician using appropriate 3/4-inch drive equipment. Ensure the drive tool and socket are fully seated before applying torque to prevent rounding of the fastener or socket damage. This socket is not rated for impact tool use unless otherwise specified by the manufacturer. Inspect the socket for cracks or wear before each use and remove from service if damage is found.
