Rubber-coated Wera hex key for inch-sized internal hex screws to protect your fingers. This provides an ergonomic and comfortable grip even in low temperatures. The Hex Plus profile offers larger contact surfaces in the screw head, minimizing the risk of rounding and nearly eliminating damage to the screw head. The ball end on the long arm allows for safe working even in difficult installation positions. The BlackLaser surface treatment ensures excellent surface protection against corrosion and a long lifespan. Laser-etched and therefore abrasion-resistant size markings on the hex key enable quick access.
