ITH Roundnuts RMS / RMZ
The stress-optimized design of ITH Roundnuts RMS and RMZ achieves higher bolt pre-tensioning forces (up to 40% more) than with comparable DIN hexagon nuts which is confirmed by scientific studies. The design is certified by German Lloyds. ITH RMS / RMZ are built to work with ITH Bolt Tensioning Cylinders from the range of M24 to M100 (7/8'' to 4''). The ITH Roundnuts are produced in:
-
ITH RMS : ITH round nut hexagon version
-
ITH RMZ: ITH round nut two-flat version
Even customized applications are possible. Both versions are also available in a flat version "ITH RMS / RMZ slim line".
ITH Round nuts can achieve up to 40% higher preloads
-
which allows the designer to reduce the fastener sizes which saves costs
-
Higher bolt spacing n: The flange diameter can be reduced which saves costs

Cost reduction 1:
-
In comparison to conventional hexagon nuts, fewer ITH RMS / RMZ nuts can be used by achieving the same pre load force (n hexagon nuts > n ITH RMS / RMZ)
Cost reduction 2:
-
The ITH RMS / RMZ can be used with the same amount of nuts to achieve a higher pre load force in the bolt connection. The bolt connection can be designed in a more effective way and therefore the material costs are reduced.
Further advantages:
-
Higher security
-
Smaller contact pressure of the bolts
-
Higher repeatability of the pre load forces by using the ITH bolt tensioning cylinders
-
Possible reduction of the tightening factor αA
