Proto JSCV16B Combination Wrench 1/2 Inch 12-point

Product Description

The PROTO JSCV16B is a 12-point combination wrench designed for professional fastener work in mechanical, HVAC, plumbing, and electrical trade applications. The open end and box end are forged from steel with a chrome finish for corrosion resistance and durability in shop or field use. The box end features a 15-degree offset angle, which provides clearance in tight spaces where a flat wrench cannot swing freely. Overall length is 7-29/32 inches. The box end head thickness measures 11/32 inches, keeping the profile low for close-clearance fasteners. This wrench is a standard hand tool carried by HVAC technicians, pipefitters, electricians, and general mechanics.

The JSCV16B fits 1/2-inch fasteners and is suited for both residential and commercial service work. The 15-degree offset box end is particularly useful when working around obstructions such as pipe runs, duct flanges, or equipment enclosures where straight-on access is limited. The 12-point box end engages fasteners at 30-degree increments, giving the technician more ratcheting positions in confined swing arcs. It is an appropriate addition to any service van or tool kit where 1/2-inch hardware is routinely encountered.

Installation Notes

This wrench is a hand tool installed and used by licensed tradespeople and mechanics. No power shutoff is required for the tool itself, but always de-energize, isolate, and lock out equipment before working on any mechanical fasteners near electrical or pressurized systems. Use the correct size wrench to avoid rounding fastener heads. Do not use a wrench as a hammer or apply extension bars to the handle beyond the tool's rated use.
