2-3/16" 12-Point Combination Wrench

The Gray Tools 3170 is a satin-chrome combination wrench built for professional mechanics and serious DIYers who need reliable fastening on large hex hardware. Its 12-point box end engages fasteners from multiple angles for quicker placement in tight spots. The open end provides standard leverage for breakaway torque. This tool suits heavy-duty automotive, industrial and agricultural maintenance.

12-Point Precision Broached Box End

The single specification that decides fit is the 12-point broached opening sized at 2-3/16". Precision broaching ensures tight, secure engagement on compatible hex fasteners, reducing the risk of rounding corners. The geometry matches ANSI dimensional standards for interchangeability. No other drive configuration or size is offered on this model.

Satin Chrome Corrosion Resistance

The satin chrome finish delivers maximum resistance against rust and chemical exposure in shop environments. It comfortably handles repeated high-torque cycles on large bolts and studs found on heavy equipment. The wrench runs out when the fastener exceeds the 2-3/16" hex size or when access demands a different drive style such as a socket or offset pattern.

Questions about this item

How does the 12 point drive engage on a 2-3/16" fastener?

The 12 point broaching allows engagement at multiple angles, giving more positioning options in tight spaces while maintaining a secure fit on the 2-3/16" hex.

What does meeting ANSI standards mean for this wrench?

Meeting ANSI standards confirms the wrench meets recognised dimensional and performance requirements for combination wrenches.

What clearance does the 2-3/16" combination wrench need to fit?

The satin chrome finish adds minimal thickness, so the wrench fits standard clearances for a 2-3/16" open end and box end.
