Proto JSCVM16B Combination Wrench 16 Mm 12 Point

Product Description

The PROTO JSCVM16B is a 16 mm combination wrench built for professional tradespeople who need a reliable, durable hand tool for fastener work in HVAC, plumbing, electrical, and general mechanical applications. It features a 12-point box end and an open end, both sized at 16 mm, with a 15-degree offset head angle that improves knuckle clearance in tight spaces. The wrench measures 9-33/64 inches overall length and is constructed from steel with a chrome finish that resists corrosion and simplifies cleanup. This tool is appropriate for any trade professional or journeyman who works with metric fasteners on equipment, piping, conduit supports, or structural hardware.

The JSCVM16B suits residential and commercial service environments where metric fasteners are standard. It is well suited for HVAC equipment installation and service, mechanical rooms, panel and conduit work, and plumbing fixture applications. The 15-degree offset and 12-point head design allow access to fasteners in confined areas where a straight wrench or socket cannot seat properly. The chrome finish makes it practical for both shop and field use.

Installation Notes

This wrench is used by HVAC technicians, plumbers, electricians, and general mechanics as a hand tool for tightening or loosening metric fasteners. Always select the correct size wrench to avoid rounding fastener heads. When working on energized electrical equipment or pressurized systems, de-energize or depressurize the system before applying any mechanical force to fasteners. Inspect the wrench for cracks or damage before each use.
