GEDORE 133 Striking Open-End Wrench 30 mm DIN 133 Manganese Phosphated

Stubborn, corroded fasteners in heavy-duty industrial settings often resist standard wrenches, leading to downtime and damaged tools. The GEDORE 133 striking open-end wrench solves this by combining a robust drop-forged design with a striking surface that allows controlled hammer blows for maximum loosening torque. Its 30 mm jaw fits a wide range of large hex fasteners, while the manganese phosphate finish provides excellent corrosion protection and a secure grip even with oily hands.

Who is it for

This wrench is built for professional mechanics, maintenance crews, and industrial technicians who regularly face seized or high-torque bolts. It is ideal for applications in construction, mining, agriculture, and heavy machinery repair where a standard wrench would fail or round off fasteners.

Main features

• Striking open-end design allows use with a hammer for extra force on stubborn nuts and bolts.
• Nominal size 30 mm (SW) fits common large hex fasteners in industrial equipment.
• Drop-forged from chrome vanadium steel 31CrV3 for exceptional strength and durability.
• Manganese phosphated finish resists corrosion and provides a non-slip, matte surface.
• Conforms to DIN 133 standard, ensuring reliable jaw dimensions and performance.
• Straight head design with flat handle for secure, comfortable grip during heavy use.
• Made in Germany by GEDORE, a trusted name in professional hand tools.

Tips

Always use a soft-faced hammer (copper, brass, or plastic) to avoid damaging the striking surface. Ensure the jaw is fully seated on the fastener before striking to prevent slippage. For extremely seized bolts, apply penetrating oil and allow it to soak before using the wrench. Store in a dry place to maintain the phosphate finish.
