L-shaped hex key set Wiha 43849 Metric 9 pcs long arm sizes 9.1-11.3 cm

Wiha 43849 L-shaped hex key set includes nine metric long-arm hex keys in luminescent colours, supplied in SB-cardboard packaging. The set is designed for improved organisation and quick identification: turning one key in the holder causes the others to swing aside, allowing fast removal of the required key while a clamping mechanism prevents keys falling out. Luminescent paint makes the keys visible under UV light. MagicRing® spring-steel retention holds standard hex screws securely in any position without magnets. Each key has a hexagonal ball end for fastening at angles up to 25°. Sizes cover the useful range for many applications.

Advantages

The ErgoStar holder design enables simultaneous movement of all keys for easy access and secure locking to prevent accidental loss. Colour coding and luminescent finish speed up tool selection and improve visibility in low-light conditions. The MagicRing® feature provides firm screw retention while the ball end allows angled entry up to 25°, increasing accessibility in confined or awkward positions.

Suitable for

• Fastening hex screws in tight or confined spaces
• Work on horizontal, inclined or deep blind holes
• Maintenance and assembly tasks requiring long-arm reach and leverage

How to use

Open the ErgoStar holder and rotate one L-key; the other keys will swing aside to allow removal of the selected key. Insert the long arm into the screw head, using the ball end if access is angled—this permits operation at up to 25°. The MagicRing® holds the screw on the key during insertion and removal. After use, return the key to the holder until it clicks into the clamping mechanism to secure it.

Usage recommendations

Use the luminescent keys with UV or in low-light conditions for faster identification. Ensure the holder is closed and clamped when transporting to avoid losing individual keys. Do not use the keys on fasteners larger than their rated sizes or apply excessive torque beyond the manufacturer's intended use.
