Proto J5534 Hand Socket 1-1/16 in 3/4 Drive 12-point

Product Description

The PROTO J5534 is a 1-1/16 inch, 12-point hand socket with a 3/4 inch drive, built for heavy-duty fastener work in mechanical and industrial applications. Manufactured from alloy steel with a chrome-plated finish, this standard-length socket measures 2 inches overall and meets ASME B107.110-2012 standards. The 12-point geometry engages fasteners at multiple positions, reducing ratchet swing arc requirements in tight spaces. Licensed trades and experienced mechanics reaching for a 3/4 drive in this size range will find this socket built to spec and ready for demanding torque loads.

The J5534 is suited for heavy equipment maintenance, fleet service, industrial machinery repair, and commercial vehicle work where 3/4 drive tooling is standard. Its standard-length profile fits typical socket rail and tool storage setups. The chrome finish resists corrosion during everyday shop and field use. Plumbers, pipefitters, millwrights, and heavy equipment technicians commonly use 3/4 drive sockets of this size when working on large fasteners found on pumps, compressors, flanges, and structural assemblies.

Installation Notes

This socket is intended for use by qualified mechanics and trade professionals familiar with 3/4 drive tooling. Ensure the socket is fully seated on the drive tool before applying torque to prevent rounding or slippage. Inspect the socket and drive tool for cracks or wear before use on high-torque fasteners. Follow applicable workplace safety guidelines and torque specifications provided by the equipment manufacturer.
