867/4 Z TORX BO Bits w/Bore Hole, TX 8 x 89 mm, Pack of 10
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 that can mount the pin. Tough, for universal use. 1/4" hexagonal, suitable for holders as per DIN ISO 1173-F 6.3.
