Proto J1193MLO 12 Point Double End Box Wrench

Product Description

The PROTO J1193MLO is a 12-point double-end box end wrench built for professional tradespeople who need reliable torque in tight spaces. Constructed from steel with a chrome finish, this wrench delivers clean engagement on fasteners through its 12-point geometry, which allows repositioning in confined areas with a narrow swing arc. The reversing design adds versatility across a range of fastener-driving and removal tasks. Weighing 0.4 pounds, it is lightweight enough for extended use without fatigue. It meets GGG-W-001405 standards and carries a lifetime warranty.

This box end wrench suits mechanical, plumbing, electrical, and HVAC service work where a secure, slip-resistant grip on hex or square fasteners is required. The double-end configuration provides two working ends in a single tool, making it practical for technicians working across multiple fastener sizes on the same job. It is equally at home in residential and commercial service environments wherever steel fasteners are encountered.
