WERA 05059569001 867/4 Z BO TORX 15 X 89 MM TIE

Premium bits for TORX® socket screws. TORX® BO screws have a protruding pin in their drive profile. This prevents unauthorized loosening, as these screws cannot be operated with "normal" TORX® tools. Only special TORX® BO tools have a bore which can mount the pin. Tough, for universal use. With colour coding by tip (green = TORX®) and size stamping for easy identification of the required bit. 1/4" hexagonal, suitable for holding tools as per DIN ISO 1173-F 6.3.
