Proto J1211MASD Combination Wrench 11 Mm 15 Degree Offset

Product Description

The PROTO J1211MASD is a 12-point combination wrench designed for professional use in mechanical, industrial, and maintenance applications. It features an 11 mm head size with a 15-degree offset angle, allowing clearance over fastener heads in tight or recessed spaces. The wrench is machined from steel with a satin finish that reduces glare and resists corrosion. At 6-29/32 inches overall length and 0.15 pounds, it delivers solid leverage without adding bulk to a tool kit. It is tether capable, making it suitable for at-height work or environments with dropped-tool hazards. Meets ASME B107.100 standards and carries a limited lifetime warranty.

This wrench fits standard 11 mm hex fasteners and is used across a wide range of trade applications including HVAC equipment assembly, plumbing fixture work, electrical panel and motor work, and general mechanical maintenance. The straight handle and offset box end make it practical for both open-space and confined fastener access. Its corrosion-resistant finish holds up in shop, field, and industrial environments. The tether-capable design meets safety requirements on job sites where tool drops present a hazard.

Installation Notes

This wrench is used by mechanics, HVAC technicians, electricians, plumbers, and general maintenance trades. Before servicing any equipment, de-energize electrical systems, relieve pressure from pressurized lines, and follow all applicable lockout/tagout procedures. Inspect the wrench for cracks or deformation before each use and do not use extension cheater bars on the handle. When tethering, verify the anchor point and tether hardware are rated for the load and drop distance of the application.
