High endurance with Wera bits

Practical benefits
  • Secure grip prevents cam-out: The diamond particle coating bites into the fastener so you avoid slippage and protect workpiece surfaces.
  • Built for impact tools: Specially engineered torsion geometry absorbs peak loads, ensuring you get extended service life during demanding fastening tasks.
  • Standard hex tool fit: The 1/4" hexagon drive and 50 mm length let you connect directly to conventional bit holders and impact drivers.

In a nutshell

The right choise for

Tackle demanding and repetitive fastening tasks with confidence using the Wera 867/4 imp DC Torx tx 20 x 50 mm bits. Engineered with Impaktor technology and an optimized torsion zone, these bits absorb extreme torque peaks from high-power impact drivers to prevent premature breakage and ensure extended service life. The rough diamond-particle coating bites securely into the screw head, effectively eliminating cam-out and slippage. Featuring a standard 1/4" hexagon drive and a 50 mm length, you easily reach recessed fastenings with superior control. This 5-piece set delivers the durability and precision you need on every 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.
