BO TX 20 X 89mm TORX BITS , Tamper Resistant

High quality bits for recessed TORX® screws. 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 BO tools have a bore hole to take up the pin. Tough viscous for universal use. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.
