High quality Kraftform Plus screwdriver. Multi-component Kraftform handle for fast and low-fatigue working. TORX? BO screws have a protruding pin in their drive profile. This prevents any unauthorised loosening since the ?normal hex tools cannot move these screws. Only special TORX? BO tools have a bore hole which can slip over the pin. The Wera Black Point tip and a complex hardening process ensure a long service life of the tip enhanced corrosion protection and an exact fit. The hexagonal anti-roll feature prevents any bothersome rolling away at the workplace. Handle markings for simplified finding and sorting of the tool.
