Professional 12-point wrench

The Gray Tools 3150 combination wrench delivers a 1-9/16 inch hex opening with a 12-point broached profile for secure fastener engagement. Its satin chrome finish provides maximum resistance against corrosion in demanding workshop environments. This new tool meets ANSI standards for dimensional accuracy and strength.

Fits large fastener applications

The 12-point geometry allows engagement at multiple angles, freeing up swing space in tight engine bays or heavy equipment assemblies. Precision broaching ensures a tight fit that reduces rounding risk on stubborn bolts. No additional adapters or drive tools are required for operation.

Sustained torque reliability

Under continuous load the broached walls maintain full contact with fastener flats, distributing stress evenly across the 12-point pattern. Satin chrome resists surface degradation from repeated exposure to solvents and moisture. The ANSI-compliant construction prevents deformation during extended high-torque use.

Questions about this item

What is the largest hex size the 12-point broach on the 3150 wrench can grip?

The broach is precision cut for a 1-9/16 inch hex, giving a tight and secure fit on that size fastener.

How much heat does the satin chrome finish dissipate during all-day use?

The wrench has no moving parts or electrical load, so it generates no measurable heat during continuous hand operation.

What drive tool must I already own to turn the 3150 combination wrench?

None — it is a hand-operated combination wrench with an open end and a 12-point box end, so no ratchet or driver is required.
