Proto J1236S Combination Wrench 1-1/8 Inch

Product Description

The PROTO J1236S is a 12-point combination wrench designed for professional-grade fastener work in industrial, mechanical, and trade environments. It features a 1-1/8 inch open and box end with a 15-degree offset head angle, giving technicians the clearance needed to work in tight or obstructed spaces. The box end uses a 12-point configuration for positive engagement on standard hex fasteners. Constructed from steel with a polished finish, the J1236S meets ASME B107.100-2010 standards and carries a lifetime warranty. It is tether capable, making it appropriate for elevated or safety-critical work areas where dropped tools present a hazard.

The J1236S is suited for mechanical, HVAC, plumbing, and industrial maintenance applications where a reliable combination wrench in the 1-1/8 inch size is required. The straight handle and offset head make it practical for both pulling torque and reaching around obstructions on equipment panels, pipe fittings, flanges, and structural hardware. Corrosion resistance adds service life in wet or chemically exposed environments. This wrench is typically used by journeymen mechanics, HVAC technicians, pipefitters, and maintenance professionals in both shop and field settings.

Installation Notes

Installation and use of this wrench requires no power-down procedure, but always confirm the fastener size matches the 1-1/8 inch head before applying torque to avoid rounding. When using in tethered applications, attach an approved tether lanyard to the designated tether point before working at height. Polished steel tools should be kept dry and wiped clean after use in corrosive environments to maintain finish integrity.
