L-shaped hex key Wiha 01404 Metric chromium-vanadium steel 20.6 cm

The Wiha 01404 L-shaped hex key is a metric Allen key made from chrome-vanadium (chromium-vanadium) steel with a chrome-plated, through-hardened blade. It has a long arm length of 20.6 cm and a short arm of 4.4 cm, weighing 133 g, and is designed to provide good leverage and access for fastening tasks.

Advantages

The chrome-vanadium steel blade is through-hardened and chrome-plated for durability and corrosion resistance. The L-shaped design offers strong torque and reach in confined spaces, while the ball end allows fastening at angles up to 25°, improving accessibility to hard-to-reach screws. The metric sizing and precise manufacturing based on ISO 2936L ensure accurate fit with fasteners.

How to use

Insert the appropriate hex end into the screw head and apply steady torque using the long or short arm depending on required leverage and clearance. For fasteners that are not aligned straight, use the ball end to engage the screw at angles up to 25°. Ensure the tool is fully seated in the screw head before applying high torque to avoid rounding the fastener.

Recommendations

Use the long arm for higher torque and the short arm for greater clearance. Avoid using the hex key as a pry bar or hammer and keep the tool clean and lightly oiled to prevent corrosion. Replace the key if the tip shows signs of wear or deformation to maintain proper fit and safety.
