Proto J5341MCF Open End Crowfoot Wrench Chrome Metric

Product Description

The PROTO J5341MCF is a metric open end crowfoot wrench with a chrome-plated finish, designed for use with standard torque wrenches and extension bars where a conventional wrench cannot reach. The crowfoot design allows technicians to apply torque to fasteners in tight or restricted spaces without requiring direct access from above. At 3.5 inches in overall length and weighing 0.59 pounds, it is a compact, durable hand tool suited for automotive, HVAC, plumbing, and general mechanical service applications. The chrome plating resists corrosion and simplifies cleanup in shop environments.

This crowfoot wrench is intended for metric fastener applications and fits a wide range of service scenarios where standard box or open end wrenches are obstructed by surrounding components. It is commonly used by automotive technicians, HVAC installers, and industrial maintenance professionals when working around brackets, hoses, or other obstructions. The tool connects to a standard drive torque wrench or ratchet extension for precise torque application.

Installation Notes

This tool is installed by mechanics and service technicians without specialty licensing but should be used following standard torque specifications for the fastener being serviced. Ensure the crowfoot is fully seated on the fastener and squarely engaged with the drive extension before applying torque. Account for the crowfoot offset angle when calculating effective torque output if precise torque is required per equipment service documentation. Store in a dry environment to preserve the chrome finish.
