Proto J1216M-T500 Combination Wrench 16 Mm Tether

Product Description

The PROTO J1216M-T500 is a 16 mm combination wrench built for trade professionals who need a reliable, full-steel hand tool that meets ASME B107.100-2010 standards. The wrench features a 15-degree offset head with a 12-point box end, allowing access to fasteners in tight or angled spaces. The chrome finish provides corrosion resistance for long service life in harsh environments. At 9-13/32 inches overall length and 0.35 pounds, it handles well for extended use in mechanical, plumbing, and electrical work. The tether-capable design supports tool-tethering programs required in elevated or confined-space work environments.

This wrench is suited for residential and commercial trade work where metric fasteners are standard. HVAC technicians, pipefitters, electricians, and millwrights will find it appropriate for equipment installation, service calls, and maintenance on metric-fastened components. The straight handle and offset head make it practical for working in equipment panels, mechanical rooms, and overhead installations where clearance is limited. It is packaged and sold individually.

Installation Notes

Use on properly sized 16 mm fasteners only — using an oversized or undersized wrench risks fastener rounding and personal injury. Power down or de-energize equipment before performing any service work on fastened assemblies. For elevated work, attach the tether point to an approved lanyard system per your site safety program. This tool is not rated for non-sparking applications.
