High-quality hex key for inch-sized internal hex screws. Hex-Plus provides larger contact surfaces in the screw head, thereby minimizing the notch effect and nearly eliminating the destruction of the screw head. The ball on the long arm allows for safe working even in difficult installation positions. The BlackLaser surface treatment ensures excellent surface protection, including against corrosion, and a long lifespan. Laser-etched and therefore abrasion-resistant size markings on the hex key allow for quick access.
