Proto J5554M Hand Socket 54 Mm 12-point 3/4 Drive

Product Description

The PROTO J5554M is a 54 mm, 12-point hand socket designed for heavy-duty fastener work in professional trade and industrial applications. Built from alloy steel with a chrome-plated finish, this socket fits a 3/4 inch drive and measures 3-9/32 inches in overall length, classifying it as a standard-length socket. The 12-point design engages hex fasteners at multiple contact positions, which is useful when swing arc is limited. It meets ASME B107.110-2012 and SAE AS955 standards, confirming dimensional and performance compliance. Licensed mechanics, industrial maintenance techs, and heavy equipment service professionals will find this socket suited to large-diameter fasteners encountered on drivetrain components, structural hardware, and industrial machinery.

This socket is appropriate for use in automotive, fleet, heavy equipment, and industrial maintenance environments where 54 mm fasteners appear on wheel hubs, axle hardware, large hydraulic fittings, or structural assemblies. The 3/4 inch drive designation makes it compatible with 3/4 drive ratchets, breaker bars, and torque wrenches commonly used in heavy-duty service bays. The standard length profile fits most open-access fastener locations without requiring an extension in typical setups.

Compatibility

Designed as a standard 3/4 inch drive hand socket for use with 3/4 drive ratchets, breaker bars, and torque wrenches requiring a 54 mm, 12-point socket.

Installation Notes

This socket is installed and used by licensed mechanics, fleet technicians, and industrial maintenance professionals. Before applying torque to any fastener, ensure the drive tool and socket are fully seated and free of debris. Do not use impact drivers with this hand socket unless the tool is specifically rated for impact use. Follow applicable workplace safety standards and equipment service specifications when loosening or torquing large fasteners.
