Gray Tools 66874 2-5/16" Striking Face Box Wrench 45° Offset Head

SKU CH-M5XB-7HDMF

A 12-point box wrench with a 45-degree offset head and large striking block for high-torque fastening in tight spaces

  • 12-point drive ensures tight, secure fit on fasteners
  • 45° offset head clears obstructions for easier access
  • Large striking block maximises safety and surface contact
  • Forged premium tool steel delivers maximum durability
  • Black oxide finish resists corrosion for longer life

2-5/16" 12-Point Striking Wrench

This 2-5/16" 12-point striking face box wrench is built for heavy-duty fastening where impact force is required. The 45-degree offset head provides clearance around obstructions common in industrial maintenance and large equipment assembly.

45° Offset Head With Striking Block

The 45-degree offset head design allows access to fasteners in confined spaces where a straight handle would interfere. A large, robust striking block ensures maximum surface contact and safety when hammer blows are applied to loosen or tighten stubborn bolts.

Forged Tool Steel With Black Oxide

Forged from premium tool steel, the wrench resists deformation under high impact loads. The corrosion-resistant black oxide finish protects the surface during storage and use. Precision broaching delivers a secure fit on 12-point fasteners, reducing the risk of rounding corners. California Proposition 65 warnings apply for chemical exposure.

Questions about this item

Does the 12-point box end on the 66874 wrench wear faster than a 6-point design under heavy striking?

The 12-point broaching distributes load across more contact faces, reducing corner rounding compared with 6-point when the 45° offset head is struck squarely.

What stops me from torquing the 2-5/16" hex beyond the forged steel's yield point during all-day use?

The large striking block maximises hammer contact area, letting the operator feel each blow so excess force is detected before the premium tool steel deforms.

How hot does the black-oxide finish get if I hammer the wrench continuously for hours?

The corrosion-resistant black oxide coating does not insulate heat; the forged steel body conducts warmth to the handle at the same rate as uncoated tool steel.
