L-shaped hex key Wiha 01210 Metric 20.6 cm long arm 1 pc

The Wiha 01210 L-shaped hex key is a metric Allen key designed for precision and durability. It has a long arm length of 20.6 cm and a short arm of 4.4 cm, weighs 100 g, and is suitable for tasks requiring reliable torque and access in confined spaces. The blade is made of through-hardened chrome-vanadium steel with a nickel-plated finish and conforms to ISO 2936L.

Advantages

The hex key offers high strength and wear resistance due to its through-hardened chrome-vanadium steel construction and nickel plating. Its L-shape with a long 20.6 cm arm provides extended reach and greater leverage while the short 4.4 cm arm allows for compact use in tight spots. Compliance with ISO 2936L ensures consistent metric dimensions and quality.

How to use

Select the correct metric size for the hex fastener, insert the short or long arm into the screw head depending on access and required torque, and turn clockwise to tighten or counterclockwise to loosen. Use the long arm for increased leverage and the short arm for higher-speed turning when clearance allows. Apply steady, even force to avoid rounding the fastener.

Recommendations

Inspect the tool and fastener for wear before use. Keep the hex key clean and dry to maintain the nickel-plated finish. Do not use cheater bars or excessive force beyond hand leverage; for very high torque applications use an appropriately sized torque wrench or socket tool.
