Williams JHW1234MSC Combination Wrench 34 Mm 12-point

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1234MSC is a 34 MM combination wrench built for trade professionals who need reliable torque transfer without fastener damage. The box end uses a 12-point SUPERTORQUE design that applies wrenching force to the flat surfaces of a hex fastener rather than the corners, reducing rounding and deformation under high torque. The open end features a SUPERCOMBO profile with grooves that redirect force away from fastener corners for the same reason. The chrome finish is high-polish and meets ANSI B107.6 and SAE AS 954 specifications. This wrench weighs 2.924 pounds and spans 17.5 inches in length.

The JHW1234MSC is suited for mechanical, HVAC, plumbing, and general trade work where large metric fasteners are common. The 34 MM opening fits heavy-duty hex fasteners found on equipment mounts, flanges, valve bodies, and structural connections. Its 12-point box end gives more engagement positions in tight access areas, and the SUPERCOMBO open end handles partially tightened or hard-to-reach fasteners without a ratchet. This wrench is sold individually and is intended for professional service use.

Key Features

Compatibility

Installation Notes

A licensed mechanic or qualified trade technician should select the correct wrench size before applying torque to avoid fastener damage. Always ensure the wrench is fully seated on the fastener before applying force. De-energize or shut off any equipment before performing mechanical work on fastener connections. Do not use extensions or cheater bars on standard combination wrenches unless the tool is rated for such use.
