Reliable screwdriving with Wera

Practical benefits
  • Reduced cam-out and slipping: The rough diamond coating bites into the fastener so you avoid slipping out of the screw head.
  • Built for impact drivers: Optimized Impaktor technology absorbs extreme load peaks to give you extended service life during heavy-duty fastening.
  • Fast profile and size identification: You locate the correct Pozidriv PZ 2 bit immediately using the color-coded Take it easy tool finder.

In a nutshell

The right choise for

Tackle heavy-duty fastening with confidence using the Wera 855/4 imp DC sb Impaktor Pozidriv bit. Engineered for use with cordless impact drivers, the Impaktor technology absorbs extreme load peaks to prevent premature bit breakage. The rough diamond coating bites firmly into the screw head, significantly reducing slipping and cam-out during high-torque applications. With its 50 mm length, you easily access fasteners in deeper recesses without needing extra adaptors. Featuring a standard 1/4" hexagon drive and the color-coded Take it easy tool finder, you instantly grab the correct pz 2 bit for the task.

Product description

High quality bits for Pozidriv* 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. Particularly suitable for use with customary impact drivers. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3. * Pozidriv = registered trademark of European Industrial Service Ltd.

  • Suitable for Pozidriv 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
  • 1/4" hexagon drive (Wera connecting series 4)

Application

  • Suitable for Pozidriv screws

Drive

  • 1/4" hexagon, suitable for DIN ISO 1173-F 6.3 bit holders

Design

  • The Impaktor technology ensures an above-average service life even under extreme conditions thanks to a best-possible utilisation of the material properties and optimally designed geometry, particularly suitable for use with conventional impact drivers, the rough diamond coating reduces the danger of any slipping out of the screw head due to the enhanced frictional resistance. Take it easy tool finder: Output colour coding (black = Pozidriv) and large stamp to enable the desired bit to be easily located.

Features and benefits

  • For an above-average service life. 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. Another product advantage is the coating of the Impaktor bits with minute diamond particles. 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.
  • For use with impact screwdrivers. Improve productivity when screwdriving with power tools.

  • Particularly high strength. Reduce the danger of premature bit breakage.
  • Torsion zone specially designed to absorb such forces and thereby protect the bit tip.
