Tube-coated Wera hex key to protect your fingers. This provides an ergonomic and comfortable grip even in low temperatures. On one side, it features a TORX® BO profile: the hole in the bit and the pin in the TORX® BO screw prevent unauthorized loosening. It is a safety screw. The ball on the long arm allows for secure work on TORX® screws even in difficult installation positions. The BlackLaser surface treatment ensures excellent surface protection, including against corrosion, and a long service life. The laser-etched and thus abrasion-resistant size marking on the hex key allows for quick access.
