Proto J1211MBASD Combination Wrench 11 Mm 15 Degree Offset

Product Description

The PROTO J1211MBASD is an 11 mm combination wrench designed for professional use in mechanical, industrial, and trade service environments. It features a 15-degree offset head on the box end, which provides knuckle clearance in confined fastener locations. The wrench measures 6-29/32 inches overall length and is constructed from steel with a corrosion-resistant finish. The tether-capable design allows it to be secured with a lanyard or tool tether system, making it appropriate for work at elevation or in environments where dropped tools are a safety concern. Licensed tradespeople and journeymen mechanics in HVAC, plumbing, and general mechanical service will find this wrench suited to everyday fastener work.

This wrench is intended for use in professional shop and field service settings where metric fasteners are standard. The 11 mm head size covers common metric bolt and nut sizes found in equipment panels, compressors, fan assemblies, and mechanical systems. The straight handle and 15-degree head offset make it practical for both open-face pulls and box-end torque applications in standard and moderately restricted spaces. The 12-point box end provides multiple engagement positions on hex fasteners, reducing the arc swing needed in tight quarters.

Installation Notes

This combination wrench should be used by qualified tradespeople following applicable safety and tool-use guidelines. Inspect the wrench for cracks, deformation, or worn points before each use and remove from service if damaged. When using at height, attach the tether point to an approved tool lanyard to prevent dropped-tool incidents.
