Wera - 867/4 Z TORX BO Bits with Bore Hole

Article description

Premium bits for TORX BO 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. 1/4“ hexagonal, suitable for holders as per DIN ISO 1173-F 6.3.

TORX with borehole (BO)

TORX tools with a borehole prevent the unauthorised unfastening of safety screws. The screws contain a pin that protrudes into the drive profile so that ”normal“ TORX tools cannot be used. This pin fits into the borehole of TORX BO tools allowing safety screws to be unfastened.

Tough bits

Tough Wera bits prevent the tip from breaking prematurely. Z-bits usually are the bit for universal screwdriving applications.
