L-shaped hex key Wiha 01398

The Wiha 01398 L-shaped hex key is a metric Allen key made from chrome-vanadium steel with through hardening and chrome plating. It has a long arm of 14.2 cm and a short arm of 2.9 cm, and weighs 17 g. The tool complies with ISO 2936L and includes a ball end that allows working at angles up to 25°, providing access to screws in tight or hard-to-reach locations.

Advantages

The chromium-vanadium blade is through hardened and chrome-plated for improved wear resistance and corrosion protection. The L-shaped design offers leverage from the long arm and compact access with the short arm. The ball end provides angular access up to 25°, making it suitable for partially obstructed screw positions. Conforms to ISO 2936L for dimensional and quality consistency.

How to use

Select the correct metric hex key size for the screw head. Insert the appropriate arm into the hex socket; use the long arm for higher torque or reach and the short arm for confined spaces. For screws not aligned with the approach, engage the ball end and operate at angles up to 25° to turn the fastener. Apply steady, controlled force to avoid rounding the screw head.

Recommendations

Use the long arm for increased leverage when loosening tight screws and the short arm when space is limited. Avoid excessive force beyond the tool's mechanical limits to prevent damage to the key or fastener. Store in a dry place to maintain the chrome plating and prevent corrosion.
