Bolt Testing Machines

The range of TesT Bolt testing machines consists of:

  • Friction coefficient testing machines (model series 205)
  • Manual friction testing equipment (model series 206)
  • Vibration testing machines (model series 208) 
  • Tensile testing machines (model series 112-115)


Friction coefficient testing machines of model series 205 by TesT are market-leading with patented components and always built according to most modern test methodologies. TesT has created an ideal instrument for the safe and fast friction coefficient testing of bolt connections for bolts from size M3 up to M80.

For simple applications TesT offers a manual alternative as a reasonably-priced and fast possibility of friction coefficient determination (model series 206). The associated software package allows simple evaluations and graphical illustrations.

As an extension to the friction testing machines TesT offers vibration testing machines for testing according to "Junker". Primarily, these machines are used for dynamic tests of safeguarding characteristics of fastening elements under transversal load (e.g. DIN 65151). A further development allows testing of larger screws, currently up to M42.
