Proto® Crowfoot Wrench, Measurement System: Metric, 13 mm Wrench Opening, Box/Single End Wrench, 1-1/2 in Overall Length, 3/8 in Drive, Specifications Met: ASME B107.21, Alloy Steel, Full Polished

• Crowfoot wrenches are used in hard-to-reach, restricted access situations where a standard wrench or ratchet cannot reach
• Anti-slip design open end (ASD)
• The arched surfaces are designed to spread the contact forces over a greater area and they keep the loads off the corners of the fastener which helps prevent fastener rounding
• Broad size range ensures the right tool for the application
• Full polish finish provides corrosion resistance and easy-to-clean surfaces
• Locking hole feature helps keep the crowfoot wrench engaged on the extension during use reducing downtime due to detachment of crowfoot in awkward spaces
• Use with locking extensions to reach into spaces too small for a mechanic's arm or where the fastener is out of site
