L-shaped hex key Wiha 01213 Metric 1 pc long arm 29.1 cm

Wiha 01213 L-shaped hex key for metric sizes, featuring a long arm of 29.1 cm and a short arm of 7 cm. The tool is made for applications that require access to recessed fasteners and additional leverage; total weight is 437 g. The blade is manufactured from chrome-vanadium steel, through-hardened and nickel-plated, and the design conforms to ISO 2936L.

Advantages

The chrome-vanadium steel blade with through-hardening offers durability and resistance to wear. Nickel plating improves corrosion protection and provides a smooth finish for easier insertion. The long arm length increases leverage for loosening tight fasteners while the short arm allows comfortable access in confined spaces. Compliance with ISO 2936L ensures dimensional accuracy for metric hex fasteners.

How to use

Insert the appropriate hex end into the socket of the fastener, using the short arm for higher torque or the long arm for greater reach and leverage. Apply steady force, keeping the key aligned with the fastener to avoid rounding the hex. For tightening, turn clockwise; for loosening, turn counterclockwise. Use controlled force and, if necessary, a torque-limiting tool when precise torque is required.

Recommendations

Store the hex key dry and clean to preserve nickel plating. Inspect the tip before use for burrs or wear; replace the tool if the hex profile is rounded. For corrosion protection, wipe with a light oil after use if exposed to moisture or corrosive environments.
