Proto J1216MASD Combination Wrench 16 Mm Satin

Product Description

The PROTO J1216MASD is a 12-point combination wrench designed for professional-grade fastener work in demanding trade environments. The open end and box end share a 16 mm head size, giving technicians two engagement options in a single tool. The box end features a 15-degree offset angle that improves knuckle clearance in tight spaces, while the satin finish reduces glare and resists corrosion. At 9-13/32 inches overall length, the wrench delivers solid leverage without excessive bulk. Built from steel and rated tether-capable, it suits applications where dropped-tool prevention is required. This wrench meets ASME B107.100 and carries a lifetime warranty.

The J1216MASD is suited for mechanical, industrial, and maintenance work where metric fasteners are standard. Tether-capable construction makes it appropriate for work at height, elevated platforms, or any jobsite with dropped-object control requirements. The straight handle and 15-degree offset box end are a common configuration for general-purpose wrench work on equipment, piping flanges, mechanical assemblies, and structural fasteners encountered across HVAC, plumbing, and industrial service trades.

Installation Notes

This wrench is used by licensed tradespeople and industrial maintenance technicians for fastener installation and removal. Ensure the correct head size is confirmed before applying torque to avoid rounding fastener flats. When used in tether applications, attach an appropriate lanyard through the tether point before beginning overhead or elevated work. Inspect the tool for cracks or deformation before each use and remove from service if damage is found.
