Proto J112224L Box End Wrench 11/16 X 3/4 Inch 12 Point

Product Description

The PROTO J112224L is a double-end box wrench designed for professional-grade fastener work in trade and industrial environments. It features two box ends sized at 11/16 inch and 3/4 inch, each with a 12-point geometry that allows engagement in tight spaces where swing arc is limited. The wrench is forged from steel with a polished finish and meets ASME B107.10 dimensional and performance standards. It is a non-ratcheting, fixed-box tool intended for use by mechanics, pipefitters, millwrights, and maintenance technicians who require a reliable hand wrench with precise fitment on standard hex fasteners.

This wrench suits residential and commercial maintenance, mechanical rooms, equipment installations, and general industrial service work. The double-end configuration gives technicians two common drive sizes in a single tool, reducing the number of hand tools needed on the job. It is sized for standard SAE hex fasteners commonly found on HVAC equipment, plumbing fixtures, pumps, motors, and structural hardware. The 12-point box profile works on both standard and slightly worn hex fasteners without the risk of rounding that an open-end wrench can introduce.

Key Features

• Double-end box design with 11/16 inch and 3/4 inch openings in one tool
• 12-point box geometry for engagement at 30-degree increments in confined spaces
• Forged steel construction for durability under high torque loads
• Polished finish resists corrosion and simplifies cleaning
• Meets ASME B107.10 wrench standards
• Backed by a lifetime warranty

Compatibility

Designed for use with standard SAE hex fasteners sized 11/16 inch and 3/4 inch across flats. Suitable for general mechanical and trade service applications where a fixed box-end wrench is required.

Installation Notes

This wrench is a hand tool requiring no power source or special installation. Always confirm the fastener size before applying torque to avoid rounding the fastener head. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found. Store in a dry location to maintain the polished finish.
