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!

  • “Take it easy" tool finder with colour coding according to profiles and size stamp – for simple and rapid accessing of the required tool.
  • Torsion zone specially designed to absorb such forces and thereby protect the bit tip.
  • These diamond particles reduce the cam-out effects – particularly high in power tool applications – which can lead to a slipping out of the screw head. The diamond particles literally bite themselves into the screw recess. This means that less contact pressure is required, something that greatly delays fatigue setting-in in power tool screwdriving jobs.
  • Particularly high strength. Reduce the danger of premature bit breakage.
  • Maximum utilisation of the material properties, a very special geometry – designed particularly to meet the extreme demands – as well a specific manufacturing process mean that Wera Impaktor tools have an above-average service life.
  • For use with impact screwdrivers. Improve productivity when screwdriving with power tools.

Product Details

840/4 IMP DC Impaktor bits, 4 x 50 mm

High quality Impaktor bits for hexagonal socket screws. The Impaktor technology offers an above-average service life even under extreme circumstances. Enhanced friction resistance, thanks to the rough diamond-particle coating on the bit tip, prevents any slipping out of the screw head. Hex-Plus ensures 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. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.

  • For socket head screws
  • Impaktor technology for above-average service life
  • Particularly suitable for use with customary impact drivers
  • Diamond coating for a secure fit in the screw, literally bites into the screwhead to prevent cam-out
  • Take it easy tool finder: colour coding according to profile and size
