Gearwrench 89119 Open End Crowfoot Wrench Set 10 Pc

Product Description

The GEARWRENCH 89119 is a 10-piece, 3/8 inch drive open end crowfoot wrench set covering metric sizes 10 mm through 19 mm. Each crowfoot features a square drive opening that accepts standard 3/8 inch drive ratchets and extensions, letting technicians reach fasteners in confined spaces where a standard open-end wrench cannot fit. The wrenches are machined from steel with a corrosion-resistant finish, meeting or exceeding ASME standards. This set is a practical addition to any mechanic, HVAC technician, or plumber who regularly works around tight plumbing fittings, fuel lines, or equipment connections that demand torque application at odd angles.

This set is suited for automotive, HVAC, and general mechanical service work where access to recessed or obstructed fasteners is required. The 10 mm through 19 mm range covers the most common metric fastener sizes encountered in residential and light commercial equipment, including fan assemblies, refrigerant line fittings, and pipe connections. It is a useful complement to a standard socket set when socket clearance is not available.

Installation Notes

These crowfoot wrenches are intended for use by qualified mechanics and trade professionals. Always confirm the correct metric size before applying torque to avoid rounding fasteners. Pair with a calibrated torque wrench when fastener torque specifications must be met. Do not use with impact drivers, as crowfoot wrenches are not rated for impact use unless explicitly stated by the manufacturer.
