What This Wrench Is

The Gray Tools 3158B is a 1-13/16 inch combination wrench built for turning large fasteners in industrial and heavy equipment maintenance. Its 12 point drive engages bolts from multiple angles for a secure grip in tight access points. A black oxide finish resists corrosion during daily shop use.

Who It Suits and Who It Does Not

Mechanics working on agricultural, construction or fleet machinery will find the opening matches common heavy-duty hardware. The offset box end clears obstructions on dense assemblies. Buyers needing smaller sizes for automotive work or compact spaces should look at other wrenches in the range.

The Specification That Decides Fit

The 1-13/16 inch hex size is the single figure that determines whether this wrench fits your fastener. Verify the bolt or nut dimension before ordering. The 12 point broach and ANSI compliance support reliable torque application on compatible hardware.

Questions about this item

Will the 1-13/16" 12-point opening fit the same fasteners as my older 12-point wrenches?

Yes, the 12-point broaching matches the ANSI profile used on standard 12-point fasteners, so it engages the same bolt heads and nuts as existing 12-point wrenches in your set.

How can I confirm the 12-point broach is precision-cut and the black oxide finish is intact after unpacking?

Inspect each of the 12 points for sharp, even edges without rounding, and verify the surface shows a uniform dark coating with no bare metal or flaking.

Does the box include only the 3158B wrench or are there extra pieces such as a holder or case?

The package contains the single 1-13/16" 12-point combination wrench; no organiser, pouch or additional hardware is included.
