Proto JSCVM27B Combination Wrench 27 Mm 12 Point

Product Description

The PROTO JSCVM27B is a 27 mm combination wrench built for professional tradespeople who need reliable fastener engagement in tight service environments. It features a 12-point box end with a 15-degree head offset angle, allowing the user to access fasteners in confined spaces where a straight wrench cannot fit. The wrench is machined from steel with a chrome finish that resists corrosion and makes cleanup straightforward. Overall length is 14-15/16 inches. At 1.45 pounds, it carries solid feel without excessive bulk. This tool is a standard in maintenance, mechanical, and industrial trade work.

This combination wrench is suited for residential and commercial mechanical work, industrial maintenance, HVAC equipment service, plumbing rough-in, and general trade applications wherever 27 mm fasteners are encountered. The open end handles quick turns in open space while the box end provides full engagement for high-torque breaking and final tightening. The 15-degree offset on the box end is particularly useful when clearing obstructions around bolt heads in equipment enclosures or framing bays.

Installation Notes

This wrench is a hand tool requiring no power source or special installation. Before servicing any mechanical system, shut off all relevant power, gas, or fluid supplies per applicable codes and site safety protocols. Use the box end for final tightening and initial breakaway to reduce the risk of fastener rounding. Inspect the wrench for cracks or finish damage before each use and do not use it as a striking tool or extension.
