Proto J5329MCF Open End Crowfoot Wrench Metric

Product Description

The PROTO J5329MCF is a metric open end crowfoot wrench finished in chrome plating. Crowfoot wrenches attach to a standard ratchet or torque wrench drive, allowing access to fasteners in tight or recessed locations where a conventional box or open end wrench cannot reach. The chrome finish resists corrosion and makes cleanup easier in shop environments. At 3.1 inches in overall length and 0.43 pounds, this wrench is compact enough for close-quarters work. It is well suited for use by automotive technicians, heavy equipment mechanics, and industrial maintenance professionals who regularly work with metric hardware in confined spaces.

This crowfoot wrench is intended for metric fastener applications in automotive, mechanical, and industrial maintenance settings. It is designed for use wherever a standard wrench cannot be positioned due to obstructions, including engine bays, hydraulic line fittings, and structural fasteners with limited clearance. The wrench pairs with any compatible square drive ratchet, extension, or torque wrench for controlled fastener engagement.

Installation Notes

Installation and fastener service using this tool should be performed by a qualified mechanic or maintenance technician. Always ensure the drive tool is fully seated in the crowfoot wrench before applying torque to prevent slippage. Verify the fastener size matches the wrench opening before use to avoid rounding the fastener or damaging the tool.
