Williams Comfort Products 7723-TH Box Wrench 12-pt 3/8x7/16

Product Description

The WILLIAMS COMFORT PRODUCTS 7723-TH is a double-ended box wrench with 12-point openings sized at 3/8 inch and 7/16 inch. Box wrenches fully surround the fastener head, reducing the chance of slippage under torque compared to open-end designs. The 12-point configuration allows the tool to engage in tighter arc swings, which is useful when working in confined spaces around equipment housings, panels, or mechanical assemblies. This wrench is sold individually and is appropriate for any trade professional who needs reliable hand-tool access to standard fractional fasteners encountered in HVAC, plumbing, and general mechanical service work.

The 7723-TH suits residential and light commercial service applications where 3/8 inch and 7/16 inch fasteners are common. Typical use cases include tightening or removing bolts on equipment brackets, access panels, fan assemblies, and piping supports. The dual-size ends reduce the number of tools a technician needs to carry for common fastener sizes in these ranges.

Installation Notes

This wrench is a hand tool used by HVAC technicians, plumbers, electricians, and general mechanical service professionals. Always ensure equipment is powered down and, where applicable, fuel or refrigerant supply is isolated before performing fastener work on live systems. Use the appropriate end for the fastener size to avoid rounding fastener heads. Follow applicable codes and manufacturer service instructions when disassembling or reassembling equipment components.
