Gray Tools 3166B Combination Wrench 2-1/16" 12 Point Black Oxide

Professional fit for large fasteners

The Gray Tools 3166B combination wrench handles 2-1/16 inch hex sizes with a 12-point broached opening. Mechanics and industrial technicians reach for it when standard wrenches fall short on heavy equipment or structural bolts.

12-point broach grips worn heads

Precision broaching creates full-flank contact that resists rounding on corroded or damaged fasteners. The black oxide coating meets ANSI standards and adds corrosion resistance for shop environments.

Works alone on oversized hardware

No adapter or extension is required; the single-piece forged body delivers direct torque on large bolts. It does not suit confined spaces where a compact ratchet or smaller wrench is needed.
