Friction Testing Machines (Model series 205)

Friction coefficient testing machines by TesT of model series 205 are market-leading, equipped with patented components and always built according to most modern test methodologies. Thus, TesT has created an instrument for safe and fast testing of screw connections for screws and bolts of M3 to M80. The determination of friction coefficients is in the focus of analysis.

TesT is market leader in this field of application and has already supplied numerous machines. In collaboration with well-known manufacturers of screws, nuts and coating materials, as well as with important large-scale users of the automotive industry and their subcontractors we have brought to market numerous innovations and patents, particularly in the area of screw tests.

The corresponding software TesTWinner® evaluates the data in real-time and compliant with the applicable standards. Different international standards or company internal standards can be used alternatively. Own customer specific requirements can be integrated into the software sequences and calculations.

Optionally can be integrated into the system:

  • Extensometers
  • Thermo chamber to heat the screw (patented)
  • Ultrasonic extensometers
  • Adaptation for tension bolts
