Wera L-keys with finger-protecting plastic sleeves. This means they are ergonomic and pleasant to grip even in cold temperatures. At one end a TORX BO profile: the bore hole in the bit and safety pin in the TORX BO screw prevents any unauthorised loosening. Tamperproof fastening. The ballpoint on the long arm allows dependable working on TORX screws even in difficult installation situations. 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.
