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.
