High-quality hex key for inch-sized internal hex screws. Hex-Plus provides larger contact surfaces in the screw head, significantly reducing the notch effect and nearly eliminating damage to the screw head. The ball end on the long arm allows for secure working even in difficult installation positions. The BlackLaser surface treatment ensures excellent surface protection against corrosion and a long service life. Laser-etched and thus abrasion-resistant size markings on the hex key enable quick access.
