Proto J1050M Offset Box End Wrench 12 Point Double End

Product Description

The PROTO J1050M is a double-end offset box end wrench built for professional tradespeople who need reliable torque in confined spaces. Constructed from steel with a polished finish, this wrench features a 12-point box end configuration on both ends, allowing engagement with fasteners at multiple angles. The offset design positions the handle away from the work surface, providing knuckle clearance and making it practical for recessed or tight-access fastener locations. It is a non-ratcheting tool, suited for applications where steady, controlled torque application is required.

This wrench is used across HVAC, plumbing, electrical, and general mechanical service work wherever hex fasteners need to be driven or loosened in tight quarters. The double-end design gives technicians two sizes in a single tool, reducing the need to swap between wrenches mid-task. The polished steel construction resists corrosion and stands up to the demands of regular shop and field use.

Installation Notes

This wrench is a hand tool requiring no installation. Technicians should ensure the correct size end is fully seated on the fastener before applying torque to prevent rounding. Power down or de-energize any equipment before performing fastener work on energized systems. Follow applicable trade codes and manufacturer service procedures when using hand tools during system maintenance or repair.
