Gray Tools 66850 1-9/16 inch 12 point striking face box wrench 45 degree offset

1-9/16 inch 12-point striking wrench

The Gray Tools 66850 is a heavy-duty striking face box wrench sized at 1-9/16 inch with a 12-point drive. Its 45-degree offset head provides clearance for fasteners in confined spaces. Forged from premium tool steel, it targets maintenance crews and industrial mechanics who must loosen seized or high-torque bolts safely.

Sustained impact loading

The large striking block distributes hammer blows across a broad surface to protect both the tool and the workpiece during repeated hits. A corrosion-resistant black oxide finish withstands exposure to moisture and chemicals over long shifts. Precision broaching maintains a secure fit on the fastener through many cycles without rounding the corners.

12-point drive configuration

The 12-point broach engages the fastener at twice the angular increments of a six-point design, allowing placement in tighter arcs. This geometry decides whether the wrench fits the specific bolt head you are turning. Buyers needing a six-point profile for maximum corner contact on damaged fasteners should select a different pattern.
