1-1/16" 12-Point Offset Striking Wrench

The Gray Tools 66834 is a 1-1/16 inch 12-point box wrench with a 45 degree offset head. It is forged from premium tool steel and finished in black oxide for corrosion resistance. Designed for technicians who need to apply impact force on large fasteners in tight spaces. The striking block provides maximum surface contact and safety during heavy use.

Installation and common issues

Place the wrench fully onto the fastener so the 12-point broach seats squarely before striking. The 45 degree offset clears obstructions but reduces swing room in very confined areas. Ensure the striking face is clean and free of oil to prevent the hammer from glancing off. Always wear eye protection because metal chips can fly when the block is hit hard.

Pre-purchase checks

Verify the fastener measures exactly 1-1/16 inch across the flats before ordering. Confirm there is enough clearance around the bolt head for the offset head and striking block profile. Check that your hammer weight and handle length suit the striking force required for the application. This product carries a California Proposition 65 warning for cancer and reproductive harm.

Questions about this item

How do I confirm the 12-point broach grips a 1-1/16" fastener correctly after setup?

Fit the wrench on the fastener; the 12-point broach should seat fully without play and the 45° offset head must clear adjacent surfaces while the striking block contacts the hammer squarely.

What comes in the box and is anything else required to use the 66834 striking wrench?

The box contains the 1-1/16" 12-point 45° offset striking face box wrench with black oxide finish; a suitable hammer is not included and must be supplied separately.

Which version of the 66834 should I choose for a 1-1/16" fastener?

The 66834 is offered in a single 1-1/16" 12-point 45° offset configuration; select this model when the fastener size matches 1-1/16".
