Proto J1185M-A Offset Box End Wrench 12 Point

Product Description

The PROTO J1185M-A is a double-end offset box end wrench built for professional trade use in mechanical, HVAC, and plumbing service work. The 12-point box end geometry provides positive engagement on standard hex fasteners and allows repositioning in tight quarters with minimal swing arc. The offset head design gives knuckle clearance when working on recessed or flush-mounted hardware. Constructed from steel with a chrome finish, the J1185M-A is designed to resist corrosion and hold up under daily shop or field use. Reversing capability adds versatility across a range of fastening applications.

This wrench suits residential and commercial mechanical service work where access to recessed fasteners is limited. The offset configuration is a common requirement when removing equipment panels, mounting brackets, and component housings in HVAC equipment, boiler rooms, and mechanical chases. The double-end configuration allows two size options in a single tool, reducing the number of pieces a tech carries to a job. Licensed HVAC technicians, plumbers, pipefitters, and general mechanical trades all find offset box end wrenches standard in their kit.
