  • Precision 12-point grip fits 3-1/16" fasteners securely

3-1/16" Striking Face Box Wrench

This 12-point box wrench features a 45° offset head and a large striking block designed for maximum safety and surface contact. It is forged from premium tool steel with a corrosion-resistant black oxide finish. The precision broached opening provides a tight, secure fit on 3-1/16" fasteners. It meets ANSI standards for professional use.

Suited for heavy maintenance and industrial assembly

Mechanics and technicians who need to apply high torque with a striking hammer on large fasteners will find this tool built for the task. The offset head clears obstructions while the robust striking face handles impact force. Buyers looking for a standard ratcheting wrench or a thin-profile spanner for tight clearances should look elsewhere.

12-point 45° offset head with striking block

The single specification that decides fit is the 3-1/16" hex size combined with the 12-point drive geometry. The 45° offset and integrated striking block define its specific application for struck torque. Verify the fastener size and drive configuration match your requirements before purchase.

Questions about this item

Which size and offset should I choose for a 3-1/16" fastener in a tight spot?

This wrench is built for a 3-1/16" hex with a 45° offset head that clears obstructions while keeping the striking face aligned for hammer blows.

What does the 12-point drive do when I am striking the wrench on heavy machinery?

The 12-point broaching gives a tight, secure fit on the fastener so the force from the striking block transfers cleanly without rounding the corners.

How does the ANSI-standard black oxide finish hold up in a corrosive shop environment?

The corrosion-resistant black oxide coating protects the forged premium tool steel, and the wrench meets ANSI standards for durability under repeated striking loads.
