Proto JSCV34B Combination Wrench 1-1/16 Inch 12 Point

Product Description

The PROTO JSCV34B is a 12-point combination wrench designed for professional-grade fastener work in mechanical, HVAC, and plumbing service applications. It features a 1-1/16 inch head size with a 15-degree offset angle, giving technicians improved knuckle clearance in tight or obstructed fastener locations. The overall length of 14-15/16 inches provides the leverage needed for high-torque applications. Constructed from steel with a chrome finish, this wrench is built for repeated use in demanding field and shop environments. Licensed tradespeople and service technicians working with larger fasteners will find the 12-point design increases contact points and reduces rounding on worn hardware.

The JSCV34B is suited for residential and commercial mechanical service work, including HVAC equipment installation, plumbing rough-in, and general equipment maintenance. The 15-degree head offset allows the wrench to function effectively on fasteners in recessed or confined spaces where a straight wrench would be impractical. Its chrome finish resists corrosion in typical shop and field conditions. This wrench is appropriate for any trade application requiring a reliable combination wrench in the 1-1/16 inch size range.

Installation Notes

This wrench is a hand tool requiring no installation. Always de-energize electrical equipment and shut off fluid systems before using hand tools on mechanical fasteners in live systems. Inspect the wrench before each use for cracks, deformation, or finish damage that could indicate structural compromise. Do not use extension cheater bars on combination wrenches, as this can exceed the tool's design load and cause failure.
