Proto J1223MBASD Combination Wrench 23 Mm Tether Capable

Product Description

The PROTO J1223MBASD is a 12-point combination wrench designed for professional fastener work in industrial, mechanical, and maintenance environments. It features a 23 mm head size with a 15-degree offset angle, which provides clearance over obstructions while keeping the handle in a comfortable working position. The wrench measures 12-7/8 inches overall length and is constructed from corrosion-resistant steel. It is tether capable, making it suitable for elevated work environments or applications where dropped-tool prevention is required. Mechanical technicians, maintenance pros, and industrial tradespeople are the primary users of this tool.

This wrench is well suited for general mechanical assembly, equipment maintenance, and industrial service work where metric fasteners are standard. The 15-degree head offset provides knuckle clearance in confined spaces, and the straight handle delivers solid torque transfer. The tether-capable design makes it appropriate for use on elevated platforms, scaffolding, and other work-at-height situations where dropped-tool control is a job-site requirement or safety policy.

Compatibility

Designed as a standard metric combination wrench compatible with 23 mm hex fasteners across industrial machinery, heavy equipment, and mechanical assemblies requiring a 12-point box end tool.

Installation Notes

This tool is intended for use by qualified mechanical technicians and tradespeople. Inspect the wrench for cracks or deformation before each use and do not use a damaged tool. When using in tethered applications, attach an approved tether lanyard to the tether point before beginning work. Do not use extension bars or cheater pipes on combination wrenches to increase leverage beyond the tool design.
