Finger Protection Each Hex key is wrapped in a colour coded plastic that makes the tool easier to use, improves grip and prevents the tool from scratching the bike frame in case of an accident. All L-keys are easily accessible due to their colour coding and size markings. For hexagonal socket screws and TORX screws. In a robust and lightweight folding pouch. Superior Finish The BlackLaser surface treatment provides outstanding surface protection, even against corrosion, and a long service life. The tools are quickly to hand thanks to the laser-engraved and thereby wear-resistant size markings on the L-keys. Holding Function The wedging forces resulting from the contact pressure between the drive tip and the screw profile securely hold the screw on the tool. Featuring an extra-long arm this allows the user to securely tighten difficult tasks. Holding function is included on sizes 3 to 8 of the Hexs keys.
