Williams Comfort Products 10717 Crowfoot Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS 10717 is a 3/8 inch drive crowfoot wrench with a 1-7/16 inch open-end jaw. Crowfoot wrenches attach to standard 3/8 inch drive ratchets and extensions, allowing access to fasteners in tight spaces where a conventional wrench or socket cannot reach. This tool is suited for HVAC technicians, plumbers, and mechanical contractors who regularly work around confined fittings, valve packing nuts, and line connections. The open-end design grips flat sides of hex fasteners and fittings without requiring the tool to rotate a full arc around the fastener head.

The 10717 is well suited for service work on residential and light commercial mechanical systems where 1-7/16 inch fasteners appear on valve bodies, union fittings, equipment mounting hardware, and similar connections. It is sold individually and is compatible with any standard 3/8 inch drive ratchet, breaker bar, or torque wrench. Trade professionals often pair crowfoot wrenches with a calibrated torque wrench when a specific fastening torque must be achieved on fittings that would otherwise be inaccessible.

Installation Notes

Crowfoot wrenches are installed by mechanics, HVAC technicians, and plumbers as a hand tool accessory requiring no special installation. Before using this wrench on any fitting or fastener within a pressurized system, ensure the system is fully depressurized and de-energized per applicable codes. When using a crowfoot wrench with a torque wrench, account for any offset angle between the crowfoot and the torque wrench drive to maintain torque accuracy. Inspect the jaw opening for wear or damage before each use.
