2-9/16" Striking Face Box Wrench

The Gray Tools 66882 is a 2-9/16" striking face box wrench designed for heavy-duty fastening where impact force is required. Its 12-point, 45° offset head allows access to fasteners in confined or awkward positions. The tool is forged from premium tool steel for maximum durability in industrial and automotive applications. It suits mechanics and technicians who need a robust striking wrench for large hex fasteners.

Thermals noise and power draw

As a non-powered hand tool, this wrench generates no heat, noise, or electrical draw during use. The black oxide finish provides corrosion resistance without affecting thermal behaviour. There are no moving parts or motors to produce sound or consume energy. Physical effort from the operator is the only input required.

12-point offset head and finish

The 12-point broached opening ensures a tight, secure fit on compatible fasteners, reducing the risk of rounding. A 45° offset head improves clearance around obstructions while the large striking block maximises safety and surface contact when struck. The corrosion-resistant black oxide finish protects the forged steel body. No additional accessories or software are included with this tool.

Questions about this item

How do I position the 45° offset head and 12-point box end on a 2-9/16" hex fastener before striking?

Slide the 12-point box end fully onto the fastener so the 45° offset clears nearby obstructions, then strike the large striking block squarely with a hammer to avoid glancing blows.

What upkeep does the black oxide finish and forged tool steel need after repeated striking?

Wipe off debris and moisture after each use, apply a light oil film to maintain the corrosion-resistant black oxide coating, and inspect the striking block for mushrooming or cracks.

At what point does the striking block show deformation under sustained heavy hammer blows?

The forged premium tool steel striking block is designed for maximum surface contact and safety, but repeated high-force impacts will eventually mushroom the block face, signalling replacement.
