Gray Tools 3184B 12-Point Wrench

The Gray Tools 3184B combination wrench offers a 2-5/8 inch hex size with a precision broached 12-point drive for secure fastener engagement. A corrosion resistant black oxide finish protects the tool surface. It meets ANSI standards for dimensional accuracy.

Professional mechanics and serious DIYers

This wrench suits technicians who require a large 12-point combination wrench for heavy-duty fastening tasks where the black oxide finish provides durability. Buyers needing smaller hex sizes or a different drive configuration should look at other options. The Proposition 65 notice applies for users in California.

12-point drive type

The 12-point drive allows engagement with fasteners at more angular positions than a 6-point design, which is useful in confined spaces. Precision broaching ensures a tight fit on the 2-5/8 inch hex. This specification determines whether the wrench matches the fastener profile required.

Will the 12-point broach on the 3184B fit older SAE bolts I keep in my shop?
