Wera 840/4 Z Tamper-proof Hex-Plus BO bits, 2.5 x 89 mm - Pack of 5 05059641001

Tough viscous Wera bits for hexagon socket screws for universal use. The Hex-Plus profile offers a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated. ¼" hexagon, suitable for holders as per DIN ISO 1173-F 6.3. Hexagon socket BO screws have a protruding pin in their drive profile. This prevents any unauthorised loosening since the "normal" hex tools cannot move these screws. ¼" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.
