12.1 Notes on IBC TopFix 200
Tightening torques for screw connections
The tightening torques for the screw connections used in the IBC TopFix200 mounting system must be
dimensioned in accordance with DIN ISO 3506, to document and archive for 10 years. Due to the difficulty
in determining the outdoor friction coefficients, dimensioning in accordance with DIN ISO 3506 can prove
difficult.
We therefore recommend the following tightening torques:
Figure 120: Pre-tension for screws
We do not recommend using a wrench as this may quickly cause you to exceed the tightening
torque. It is sufficient to use a torque wrench or a hex spanner with T-grip.
Important!
When using laminate clamps, please clarify the tightening torque for the corresponding assembly situation
with the laminate manufacturer.
