- For hexagonal socket head screws
- Hex-Plus allows socket head screws to live longer
- Tough for hard materials
- 1/4" hexagon drive (Wera connecting series 4)
Tough Wera bits for hexagonal socket screws, for universal use. Hex-Plus offers larger contact surfaces in the screw head. The notch
effect is reduced to a minimum and the destruction of the screw is nearly eliminated. 1/4" hexagonal, suitable for holders as per DIN ISO 1173-F 6.3.
Hex-Plus: Hexagon socket screws are a
problem, because the contact
surfaces that transfer the force of
the tool to the screw are very
narrow. The consequence: the
head of the screw can be
damaged, usually rounding out the
recess. Hex-Plus tools have larger
contact surfaces to prevent this,
driving from the flats of the recess,
rather than the corners. Good to
know: Hex-Plus tools fit into every
standard hexagon socket screw!
Tough bits: Tough Wera bits prevent the tip
from breaking prematurely. Z-bits
usually are the bit for universal
screwdriving applications.
