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 notch effect and nearly eliminating the destruction of 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, including against corrosion, and a long lifespan. Laser-etched, abrasion-resistant size markings on the hex key enable quick access.
