Fast amortization

  • External calibration of torque wrenches is becoming more and more expensive.
  • It can also unnecessarily tie up capital because you may need to have spares for the time you are without your tools.
  • That's why investing in your own calibration units pays off faster than you think - especially if you use torque tools that need to be calibrated on a daily basis!

Increasing requirements.

A calibration unit from STAHLWILLE makes an important contribution to making your business more efficient, more profitable and more safe. Today more than ever, because the demands on standard-compliant tightening and bolting are high.

The quality management standard DIN EN ISO 9001 requires all companies to produce a quality management manual, which requires, among other things, the regular calibration of torque tools.
DIN EN ISO 6789:2017
DIN EN ISO 6789 regulates the method and measurement equipment used for the recalibration of hand torque tools, and since 2017 also considers measurement uncertainties in addition to measurement error. Calibration can therefore be more time consuming and complex than it used to be. However, users of STAHLWILLE calibration units still benefit from efficient and effortless calibration.
For tools used in series production, tool-related machine capability testing (MFU) according to VDI/VDE-2645-2 is becoming increasingly popular. However, this alternative to traditional calibration requires extensive measurement runs. With the appropriate module from STAHLWILLE, you can still perform them quickly and efficiently.
IATF 16949
