Williams Comfort Products JHW1213MRS 13MM Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1213MRS is a 13 mm, 12-point ratcheting combination wrench designed for professional trade use in mechanical, HVAC, and industrial service applications. The open end uses a SUPERCOMBO profile with directional grooves that shift wrenching force away from fastener corners, reducing the chance of rounding. The box end features a SUPERTORQUE design that contacts flat surfaces behind the hex points rather than the corners, allowing higher torque application without fastener damage. The ratcheting mechanism includes up to 80 teeth, which shortens the required swing arc for use in confined spaces.

This wrench is suited for residential and commercial mechanical work where metric fasteners are common, including HVAC equipment installation, refrigeration service, plumbing fixture work, and general equipment maintenance. The handle length is sized for improved leverage and balance, making it practical for both open-area and restricted-access fastener work. It is sold individually and is appropriate for use by licensed tradespeople and experienced technicians working with metric hardware.

Installation Notes

This wrench is used by HVAC technicians, plumbers, electricians, and general mechanical tradespeople. Always ensure the wrench opening is fully seated on the fastener before applying torque. When using the ratcheting box end, confirm the ratchet direction is set correctly before operation. Inspect the tool for wear or damage before each use and do not use extension bars or cheater pipes on the handle.
