Williams JHW10711 Crowfoot Wrench 3/8 Drive 1-1/16

Product Description

The WILLIAMS JHW10711 is a 6-point crowfoot wrench designed for 3/8 inch drive ratchets and extensions. It opens at 1-1/16 inches and is built from high-polished chrome steel for corrosion resistance and long service life. At 2.0 inches overall length, this wrench reaches fasteners in confined spaces where standard open-end or box-end wrenches cannot seat. Mechanics, HVAC technicians, and plumbers use crowfoot wrenches when a straight-line pull is needed on fittings, line nuts, and hex fasteners that sit behind hoses, brackets, or tubing.

This crowfoot fits standard 3/8 inch drive tool sets and is suited for residential and light commercial service work. Typical applications include tightening flare and compression fittings on refrigerant lines, hydraulic connections, fuel line nuts, and plumbing supply stops where clearance is restricted. The 6-point head geometry reduces fastener rounding compared to 12-point designs, making it a reliable choice for stubborn or corroded hardware.

Key Features

• 3/8 inch square drive accepts standard ratchets, breaker bars, and torque wrenches
• 1-1/16 inch wrench opening fits SAE fasteners and fittings
• 6-point head design minimizes slippage and fastener rounding
• High-polished chrome finish resists corrosion in wet or chemical environments
• 1-3/4 inch head diameter with 3/8 inch head thickness for tight clearance access
• 2.0 inch overall length keeps the profile compact in confined spaces

Compatibility

Designed as a direct-fit crowfoot wrench for any 3/8 inch drive ratchet, extension, or torque wrench using the SAE inch measurement system.

Installation Notes

Install using a calibrated torque wrench when connecting refrigerant line fittings or hydraulic lines that have a specified torque requirement per the equipment manufacturer. Ensure the drive connection is fully seated before applying force to prevent the wrench from dislodging under load. This tool is not insulated and is not rated for non-sparking environments — do not use near energized conductors or flammable gases without appropriate controls in place.
