High-quality hex key for inch-sized internal hex screws. Hex-Plus offers larger contact surfaces in the screw head, which minimizes notching effects and nearly eliminates 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 provides excellent surface protection, including against corrosion, and ensures a long lifespan. Laser-engraved and thus abrasion-resistant size markings on the hex key allow for quick access.
