Gray Tools 66858 1-13/16" 12-Point 45° Offset Striking Face Box Wrench

SKU CH-AN17-14WN6

A 12-point box wrench with a 45-degree offset head and striking face for high-torque applications

  • 12-point drive grips fasteners securely
  • 45° offset head clears obstacles easily
  • Large striking block transfers hammer force safely
  • Black oxide finish resists corrosion on the job
  • Forged premium steel withstands heavy-duty use

1-13/16" 12-Point Offset Striking Wrench

This striking face box wrench fits a 1-13/16 inch fastener with a 12-point broached opening. The 45-degree offset head provides clearance around obstructions. Forged from premium tool steel, it is built for heavy industrial maintenance and construction tasks.

Black Oxide Finish and Large Striking Block

The corrosion resistant black oxide coating protects the steel in harsh environments. A large, robust striking block delivers maximum surface contact and safety when impact force is applied. Precision broaching ensures a tight, secure fit that resists rounding the fastener.

Upgrading From Standard Box Wrenches

This tool replaces standard box wrenches when high torque or struck impact is required to break loose seized fasteners. The jump is worth it for mechanics and pipefitters who regularly encounter rusted or overtightened hardware needing controlled hammer blows. || This tool is not for buyers who need a ratcheting mechanism or a thin-profile wrench for tight clearances without striking capability.

Questions about this item

How do I install the 1-13/16" 12-point 45° offset striking face box wrench and what step is commonly missed?

Position the 12-point opening over the fastener, align the 45° offset head for clearance, then strike the large striking block squarely with a hammer; the step often missed is ensuring the wrench sits fully seated before striking to avoid rounding the fastener.

What maintenance or replacement will the Gray Tools 66858 wrench need over time?

Inspect the black oxide finish regularly for wear or corrosion; if the 12-point broaching shows rounding or the striking block deforms, replace the wrench to maintain a secure fit and safe impact transfer.

What limit appears first when the 1-13/16" striking wrench is used continuously under heavy loads?

The black oxide coating and striking block surface will show wear first under sustained impact, reducing corrosion resistance and contact area before the forged tool steel body reaches its durability limit.
