High quality L-keys for recessed TORX® screws. 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. Comes with extra-long arm. 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.
