Williams Comfort Products 7038-TH 12-point Box Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS 7038-TH is a 12-point box wrench sized at 1-1/8 inches by 1-3/16 inches. This double-ended box wrench provides a fully enclosed, 12-point contact on fastener heads, reducing the chance of rounding during high-torque applications. At 1.66 pounds, it offers solid heft for controlled wrenching force. Plumbers, HVAC technicians, and pipefitters reach for this wrench when working on hex fasteners, fittings, and mechanical connections that require a secure grip and repeatable engagement. It is suited for both installation and service tasks where open-end or adjustable wrenches may slip or lack the needed contact area.

This wrench is used across residential and light commercial trade applications including HVAC equipment installation, plumbing rough-in and trim-out, and general mechanical service. The two different end sizes, 1-1/8 inches and 1-3/16 inches, make it useful when adjacent fastener sizes are encountered on the same job without swapping tools. It is a hand tool suited for any technician working with larger hex fasteners common in mechanical systems.

Installation Notes

No power-down or system shutoff is required for hand tool use, but always de-energize and isolate any mechanical system before loosening or tightening fasteners on live equipment. Use the correctly sized box end to avoid fastener rounding, and apply steady, controlled force rather than shock loading. This wrench is intended for hand use only and should not be struck or used as a pry bar.
