2-13/16" Striking Face Box Wrench

This 2-13/16" striking face box wrench is built for heavy-duty fastening where impact force is required. The 12 point drive engages fasteners securely while the 45° offset head provides clearance around obstructions. It suits maintenance technicians and industrial mechanics working on large equipment.

Large Striking Block and Black Oxide Finish

A large, robust striking block maximises safety and surface contact when the wrench is struck with a hammer. The corrosion resistant black oxide finish protects the forged premium tool steel from rust during storage and use. Precision broaching ensures a tight, secure fit on the fastener.

Meets ANSI Standards for Industrial Use

This wrench meets ANSI standards for quality and dimensional accuracy. The forged construction delivers maximum durability under repeated impact loads. Buyers needing ratcheting action or a smaller profile for tight clearances should select a different tool style. The offset head design frees knuckle space on large flange assemblies.

Questions about this item

How do I position the 45° offset head when striking the 12-point box end on a 2-13/16" fastener?

Align the wrench so the offset clears obstructions, seat the 12-point box fully on the fastener, then strike the large striking block squarely with a hammer; the angled head keeps your hand clear of the work surface.

Will the black oxide finish on this 66890 wrench need re-coating after heavy use?

The corrosion-resistant black oxide is a surface treatment that wears gradually; if rust appears, clean with a wire brush and apply a light machine oil — no factory re-coating service is required.

At what point does the striking block on this 2-13/16" wrench deform under repeated hammer blows?

The forged premium tool steel block is sized for maximum surface contact; deformation depends on hammer force and fastener condition, so inspect the striking face regularly and replace the wrench if the block mushrooms or cracks.
