Advantages
As a result of the shrinkage of the ShrinkNut Nutbody the following advantages occur compared to regular threaded connections:
- No loosening of the connection – even with steady vibration influences
- Higher and torsion free pretensioning of bolts
- Decreased rupture risk due to perfect load distribution over the whole nut height
- 100% thread contact due to opimised TTG
- Maintenance free connection
- Dimensions similar to standard hexagonal nuts
- Standard bolts, thread sizes and thread pitches of any kind can be used
