Proto J5322M Deep Hand Socket 22mm 12-point 1/2 Drive

Product Description

The PROTO J5322M is a deep hand socket designed for professional trade use in mechanical, industrial, and maintenance applications. Built from alloy steel with a chrome-plated finish, this 22 mm socket features a 12-point configuration and a 1/2 inch drive, making it well suited for high-torque fastener work where access depth is a factor. The deep length profile — 3.25 inches overall — allows the socket to seat fully over longer fasteners, studs, and recessed bolt heads that standard-length sockets cannot reach. At 0.53 pounds, it is solid in hand without adding unnecessary bulk to a kit.

This socket is a standard choice for automotive repair, fleet maintenance, equipment service, and industrial assembly work wherever a 22 mm deep socket with 1/2 inch drive is required. The 12-point design engages a wider range of fastener positions, which is useful in confined spaces where ratchet swing angle is limited. It is not tether capable, so it is suited for general shop and ground-level work rather than elevated or overhead applications where dropped-tool hazards apply.

Key Features

• 22 mm socket size with 12-point contact for flexible fastener engagement
• 1/2 inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Deep length profile at 3.25 inches overall for extended fastener reach
• Alloy steel construction with chrome-plated finish for corrosion resistance and durability
• Meets ASME B107.110-2012 and SAE AS955 standards
• Compact cross-section — 0.9 inches wide — for tighter clearance access

Compatibility

Designed for use with 1/2 inch drive ratchets, breaker bars, torque wrenches, and impact-rated drive tools where compatible. Fits 22 mm hex fasteners in automotive, industrial, and equipment maintenance applications.

Installation Notes

This socket is intended for use by qualified mechanics and maintenance technicians. Always ensure the drive tool and socket are fully engaged before applying torque. Inspect the socket for cracks or wear before each use and do not use damaged sockets. This part is not tether capable and should not be used in overhead or elevated work areas where a dropped tool presents a hazard.
