Proto J5116 Crowfoot Wrench 1/2 in 3/8 in Drive 12 Pt

Product Description

The PROTO J5116 is a 1/2-inch crowfoot wrench built for 3/8-inch drive ratchets and extensions. It delivers 12-point engagement on hex fasteners in tight spaces where a standard open-end or box wrench cannot seat. The chrome-plated finish resists corrosion and simplifies cleanup in shop and field environments. At 2-25/32 inches overall length, the J5116 is compact enough for confined engine bays, mechanical rooms, and equipment access panels. Licensed mechanics, industrial maintenance technicians, and HVAC service pros reach for crowfoot wrenches when clearance is limited and torque accuracy is required.

The J5116 is suited for automotive, HVAC, plumbing, and general mechanical applications where a standard wrench profile will not clear surrounding components. It pairs with any standard 3/8-inch drive torque wrench, ratchet, or extension, making it a straightforward addition to an existing socket set. The 1/2-inch wrench size targets fastener sizes common in residential and light commercial mechanical equipment installations and service work.

Installation Notes

Always de-energize or shut off the equipment being serviced before using hand tools in tight mechanical spaces. Seat the crowfoot fully on the fastener before applying torque to avoid rounding the fastener head. When used with a torque wrench at an offset angle, consult the torque wrench manufacturer for any correction factor applicable to your setup. This tool is intended for professional service use by qualified tradespeople.
