SUPERBOLT® STRAMMERE

Bruk mekanisk stramming for å bryte ned høye krav til forspenning til lettere momentverdier. Med denne mesterlig enkle designen er det tilstrekkelig med vanlig håndverktøy for å løse alle bolteutfordringer.

Leave behind the hassle of tightening your joints, regardless of preload requirements. Superbolt offers the safest and most accurate mechanical tensioning technology. When it comes to your unique applications and obstacles, our global team of engineers can conquer any challenge.

Superbolt tensioners are designed as direct replacements for conventional nuts and bolts. These devices can be threaded onto a new or existing bolt, stud, threaded rod or shaft. The main thread serves to position the tensioner on the bolt or stud against the hardened washer and the loadbearing surface. Once it is positioned, actual tensioning of the bolt or stud is accomplished with simple hand tools by torquing the jackbolts which encircle the main thread. The jackbolts transfer the preload evenly into the main thread and, consequently, onto the joint. The main thread is tightened in pure tension.
