Proto JSCV36B Combination Wrench 1-1/8 Inch 12-point

Product Description

The PROTO JSCV36B is a 12-point combination wrench designed for professional-grade fastener work in mechanical, plumbing, HVAC, and electrical trade applications. It features a 1-1/8 inch head size with a 15-degree offset angle on the box end, allowing clearance over fastener heads in tight or obstructed spaces. The wrench is manufactured from steel with a chrome finish that resists corrosion and wipes clean in the field. At 15-7/8 inches overall length, it delivers the leverage needed for larger fasteners without excessive handle bulk. Licensed tradespeople and service technicians keep this size in rotation for mechanical connections, flanged fittings, and structural fasteners.

This wrench is suited for residential and commercial service work wherever 1-1/8 inch fasteners appear. Common applications include equipment mounting hardware, pipe flanges, structural bolting, and conduit fittings. The 15-degree offset box end is especially useful when working against panels, walls, or equipment frames where a flat wrench cannot clear the surrounding surface. The open end allows fast positioning on hex fasteners in open runs.

Installation Notes

This wrench is a hand tool used by licensed HVAC technicians, plumbers, electricians, and general mechanical tradespeople. Always confirm fastener size before applying torque to avoid rounding. When working near energized equipment, de-energize and lock out the circuit per applicable NFPA 70E procedures before using any hand tool on electrical enclosures. Chrome-finished wrenches should be wiped dry after use to maintain finish condition.
