Proto JSCRM16 Combination Wrench 16 Mm Ratcheting

Product Description

The PROTO JSCRM16 is a 16 mm combination wrench built for professional tradespeople who need reliable torque transfer in tight, high-cycle environments. The wrench features a 12-point ratcheting box end with a 15-degree offset head angle, allowing mechanics, pipefitters, and maintenance technicians to work in confined spaces without repositioning the tool on every swing. The open end is fixed. The chrome finish provides corrosion resistance, and the wrench is tether capable for use in elevated or safety-sensitive work environments. Overall length is 8-3/16 inches and the unit weighs 0.32 pounds.

This wrench is suited for mechanical maintenance, industrial service, and construction applications where metric fasteners are standard. The ratcheting box end reduces stroke angle requirements, making it practical in areas with limited swing clearance. The tether-capable design meets the safety requirements of work-at-height environments including elevated platforms, towers, and overhead mechanical rooms. The straight handle keeps the grip profile low, which helps when accessing recessed fasteners on equipment frames, flanges, and structural assemblies.

Compatibility

Designed for use with 16 mm hex fasteners in metric applications across mechanical, industrial, and construction trades.

Installation Notes

This wrench is a hand tool requiring no special installation. De-energize or depressurize any equipment before loosening or tightening fasteners as required by applicable safety codes. In tether-required work zones, attach the wrench to an approved tool lanyard or tether anchor point before beginning work. Inspect the chrome finish and ratcheting mechanism for wear or damage before each use and remove from service if the mechanism skips or the head shows cracking.
