High-quality hex key with extra short arms for use on hard-to-reach screws. Designed for internal hex screws. Hex-Plus provides larger contact surfaces in the screw head, minimizing notching 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 carefully chrome-plated finish ensures high corrosion protection. Laser-etched and thus abrasion-resistant size markings on the hex key for quick access.
