Gray Tools 3164B 2" 12-Point Combination Wrench

Professional Grade Wrench

The Gray Tools 3164B is a 12-point combination wrench built for professional mechanics and serious DIYers who need reliable fastening on large hardware. Its 2-inch opening handles heavy-duty bolts found on industrial equipment, agricultural machinery and commercial vehicles. The black oxide finish resists corrosion in shop environments. It meets ANSI standards for dimensional accuracy and strength.

Twelve Point Precision Broaching

The 12-point drive is precision broached to deliver a tight, secure fit on fastener flats, reducing rounding risk compared to worn or stamped alternatives. This geometry allows engagement at finer angles, which is the single specification that determines whether the wrench works in confined spaces where a 6-point tool cannot swing. The broaching quality directly affects torque transfer and fastener life on 2-inch hardware.

Large Fastener Tool Kit Addition

This wrench fills the upper end of a professional set, covering the 2-inch hex size that smaller assortments omit. It requires no power source, batteries or specialised sockets — only hand force and access to the bolt head or nut. Adding it frees up adjustable wrenches for odd sizes and prevents improvisation with pipes or cheater bars that damage finish and compromise safety.
