High-quality hex key with an extra short arm for use on hard-to-reach screws. Designed for internal hex screws. Hex-Plus provides larger contact surfaces in the screw head, significantly reducing notching effects and nearly eliminating damage to 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 resistance. Laser-etched and therefore abrasion-resistant size markings on the hex key for quick access.
