Description
Tough viscous Wera bits for hexagon socket screws and universal use. Hex-Plus 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. 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-D 6.3.![](https://cdn.shopify.com/s/files/1/0120/6950/3035/files/rust_free_1.jpg?v=1656005485)
