High quality L-key set with colour coded, convenient plastic sleeve. This ensures that the tool is quickly to hand and the ergonomic and pleasant handle is easy on the hands even at low temperatures. The wear-resistant clip material ensures secure storage of the L-keys as well as simple removal. The Hex-Plus profile offers a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated. The ballpoint on the long arm allows dependable working even in difficult installation situations. The holding function holds screws securely on the tool. The BlackLaser surface treatment provides outstanding surface protection, even against corrosion, and a long service life. Laser-engraved and thereby wear-resistant size markings on the L-keys for rapid accessing.
