Proto JSCVM21B Combination Wrench 21 Mm 12-point

Product Description

The PROTO JSCVM21B is a 21 mm combination wrench built for professional tradespeople who need a reliable, long-service hand tool for mechanical assembly, maintenance, and repair work. It features a 12-point box end and an open end on the same shaft, with a 15-degree head offset angle that clears obstructions and improves swing arc in tight spaces. The wrench is forged steel with a chrome finish and measures 11-13/16 inches overall length. It carries a limited lifetime warranty, reflecting the durability expected from a professional-grade hand tool.

This wrench is suited for mechanical, industrial, and trade applications where standard metric fastener sizes are encountered. The 21 mm head size is common on automotive, HVAC equipment mounting hardware, heavy machinery, and structural fasteners. The 15-degree offset allows access to recessed fasteners on engine assemblies, ductwork frames, and equipment panels where a flat wrench would lose clearance. Electricians, pipefitters, HVAC technicians, and general maintenance mechanics will find this wrench useful across a wide range of service tasks.

Key Features

Compatibility

Designed as a standard metric combination wrench for use with 21 mm fasteners across mechanical, industrial, and trade service applications.

Installation Notes

This wrench is a hand tool requiring no installation. Use it to drive or loosen 21 mm fasteners in the appropriate service context. Always confirm fastener size before applying force to avoid rounding hardware. De-energize and isolate equipment before performing any mechanical service work where this tool will be used.
