The first bolt for torsion-free tensioning especially at high temperatures > 350 °C
The SmartSTUD is a bolt with three components that is tightened without torsion. The bolt is designed either as waisted shank or full-shank bolt. With this simple design of the system, it is possible to tension axially and free from torsional or lateral forces for the first time. The dimensions of the SmartSTUD have been optimized so that the outer diameter corresponds to Inbus bolts and capped nuts in accordance with DIN 2510. Therefore, the SmartSTUD is creep resistant up to 600 °C.
