Williams JHW10724 Open End Crowfoot Wrench 1-7/8in

Product Description

The WILLIAMS JHW10724 is a 1-7/8 inch open end crowfoot wrench with a 3/8 inch square drive, built for reaching fasteners in confined spaces where a standard box or combination wrench cannot fit. Constructed from steel with a high-polished chrome finish, this wrench delivers corrosion resistance and durability under regular shop and field use. The 6-point head design reduces fastener rounding compared to 12-point configurations. At 2-3/4 inches overall length and weighing under half a pound, it is a compact addition to any torque wrench or ratchet extension setup used by HVAC technicians, plumbers, and mechanical contractors.

Crowfoot wrenches of this type are commonly used in HVAC, plumbing, and general mechanical work where access is restricted by adjacent components, hoses, or structural framing. The 3/8 inch drive accepts standard 3/8 inch drive torque wrenches and ratchets, making it straightforward to apply controlled torque to line fittings, flare nuts, and hex fasteners in tight installations. This size is particularly useful on larger refrigerant line connections and plumbing fittings where 1-7/8 inch across-flats sizing is specified.

Key Features

• 1-7/8 inch open end wrench head for larger fittings and fasteners
• 3/8 inch square drive compatibility with standard ratchets and torque wrenches
• 6-point head geometry reduces risk of rounding fastener flats
• High-polished chrome finish over steel for corrosion resistance
• Compact 2-3/4 inch overall length for access in restricted spaces
• Not insulated and not tether-capable — standard service tool application

Compatibility

Designed as a standard 3/8 inch drive open end crowfoot wrench suitable for use with any 3/8 inch drive ratchet, extension, or torque wrench in HVAC, plumbing, and mechanical service applications.

Installation Notes

This tool is installed by HVAC technicians, plumbers, and mechanical contractors as part of a 3/8 inch drive set. Always ensure the crowfoot is fully seated on the fastener before applying torque to prevent slippage. When used with a torque wrench at an offset angle, apply the appropriate angle correction factor per standard torque calculation practice. Keep the tool free of oil buildup on the drive socket to maintain secure engagement with the ratchet or torque wrench.
