Heavy-duty fastening with Wera bits

Practical benefits
  • Secure grip prevents cam-out: The rough diamond coating bites into the screw head to prevent slipping during intense driving tasks.
  • Built for impact drivers: With specialized Impaktor technology, you achieve above-average service life even under extreme working loads.
  • Instant size identification: The Take It Easy color-coding system helps you locate the correct TX 40 bit right away.

In a nutshell

The right choise for

Tackle heavy fastening tasks with confidence using the Wera 867/4 imp DC Impaktor Torx bits. Engineered with Impaktor technology, these 50 mm tx 40 bits absorb extreme peak loads from impact drivers, preventing premature breakage and extending tool life. The diamond-particle coating bites securely into the fastener head, virtually eliminating cam-out and slippage during demanding driving applications. Featuring a standard 1/4" hexagon drive and the Take It Easy color-coding system, these bits fit right into your bit holders and let you pick the correct size instantly on the job.

Product description

High quality bits for recessed TORX® 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.

  • For recessed TORX® 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

  • TORX® socket 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 (green = TORX®) 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.
  • 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.
  • Particularly high strength. Reduce the danger of premature bit breakage.
  • Torsion zone specially designed to absorb such forces and thereby protect the bit tip.
