Williams Comfort Products JHWBCOM12 Crowfoot Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHWBCOM12 is an open end crowfoot wrench designed for 3/8 inch drive ratchets and torque wrenches. It features a 12 MM wrench opening in a satin-chrome finish, making it well suited for fastener access in tight spaces where a standard box or open end wrench cannot fit. The overall length is 0.25 inches with a head depth of 0.5 inches and a length of centers measuring 0.8125 inches. Weighing just 0.08 pounds, this is a compact, purpose-built specialty wrench for metric fastener work in mechanical and industrial service environments.

Crowfoot wrenches are used when torque must be applied to a fastener that is recessed, obstructed, or positioned where a conventional wrench handle would interfere. This 12 MM open end crowfoot is a common tool in HVAC, plumbing, automotive, and general mechanical service. It is particularly useful for fitting connections, manifold fittings, and component mounting hardware where access is restricted. The 3/8 inch drive allows compatibility with standard ratchets, flex handles, and torque wrenches already common in a trade technician toolkit.

Key Features

• Open end crowfoot design for access to fasteners in confined or obstructed locations
• 3/8 inch drive fits standard ratchets and torque wrenches
• 12 MM metric opening for use on metric fasteners
• Satin-chrome finish provides corrosion resistance and low glare
• Outside diameter of 1 inch with a compact head depth of 0.5 inches
• Lightweight at 0.08 pounds for reduced hand fatigue during overhead or confined-space work

Compatibility

Designed for use with 3/8 inch drive ratchets, torque wrenches, and extensions as an open end crowfoot wrench for 12 MM metric fasteners.

Installation Notes

This wrench is installed onto a 3/8 inch drive ratchet or torque wrench without a retaining pin — ensure the drive square is fully seated in the crowfoot before applying torque. When using with a torque wrench, apply a correction factor if the crowfoot extends the effective length of the torque wrench. De-energize or shut off systems before working on fasteners on pressurized or live components. This tool is intended for use by qualified trade professionals familiar with proper torque application procedures.
