Flexnuts

Flexnuts

Superbolt was de eerste ter wereld die, met de multi-jackbolt tensioner technologie, een revolutie teweegbracht op het gebied van bouten en moeren. Sindsdien wordt deze technologie succesvol toegepast op tienduizenden installaties. Natuurlijk blijven we nieuwe oplossingen ontwikkelen voor de boutbevestigingen van morgen.

Flexnuts

Flexnuts have been specially developed for through-hole applications. Their reactive design distributes the bolt load along many threads, adds elasticity and prevents stress concentrations in the first few threads.

This helps relieve stress concentrations and increases the fatigue life of the bolt. Since Flexnuts are reactive nuts to be used opposite our tensioners, they are never torqued directly to achieve preload.

Standard series

  • Temperature range: -10 to 250ºC (0 to 500ºF)

 

Advantages

  • Ensures an equal load distribution on the thread of the bolt/stud, under load
  • Adds elasticity in the joint
  • Increases the fatigue life of the bolt/stud
