SKU CH-RE75-MQ649

  • Strike-free design with add-on bar multiplies torque safely
  • Premium forged steel resists wear under heavy use

1-3/8" 12-Point Offset Wrench

This new Gray Tools 66644 wrench fits 1-3/8 inch fasteners with a 12-point drive. The 45-degree offset head provides clearance in confined spaces. A strike-free design allows an add-on bar to multiply torque safely. It suits technicians who need reliable leverage on large, stubborn bolts.

Upgrade from standard striking wrenches

A conventional striking wrench requires hammer blows that can damage components or injure the user. This tool replaces that method by accepting a leverage bar for controlled force. The jump is worth it when fastener size or access makes impact tools impractical or unsafe. Precision broaching ensures a secure fit that reduces rounding risk.

Black oxide finish for corrosion resistance

Forged from premium tool steel, the wrench meets ANSI standards for durability. The corrosion-resistant black oxide coating protects the surface in harsh environments. It fits directly onto the fastener without adapters, freeing up tool-bag space. Buyers who need smaller hex sizes or a ratcheting mechanism should look elsewhere.
