Proto J1216MH-T500 Combination Wrench 16 Mm

Product Description

The PROTO J1216MH-T500 is a 16 mm combination wrench built for professional tradespeople who need a reliable, corrosion-resistant hand tool in demanding service environments. The wrench features a 15-degree offset head angle on both the open and box ends, a straight handle, and a 6-point box end profile that grips fastener flats rather than corners to reduce rounding. At 9-13/32 inches overall length and 0.37 pounds, it is sized for moderate torque applications in tight spaces. The chrome finish resists corrosion, and the tool meets ASME B107.100 standards. It is tether capable, supporting drop-prevention requirements in elevated or overhead work environments.

This wrench is suited for residential and commercial mechanical work, including HVAC equipment service, plumbing rough-in and trim, electrical panel work, and general mechanical assembly. The tether-capable design makes it appropriate for rooftop HVAC units, elevated platforms, and industrial sites where dropped-tool policies are enforced. Licensed technicians, journeymen, and experienced service pros working on metric fasteners will find this a direct fit for everyday service kits.

Installation Notes

This wrench is a hand tool used by HVAC technicians, plumbers, electricians, and general mechanical tradespeople. Always de-energize, lock out, and tag out equipment before performing fastener work on electrical or mechanical systems. When working at height or in overhead environments, attach an approved tether to the tether point before use to comply with dropped-object prevention requirements. Inspect the wrench before each use and do not use if the jaws or box end show signs of damage or wear.
