Decoupling Nut

 

In today's engines higher requirements are placed on fasteners. To meet these requirements, a specially designed nut is developed - the decoupling nut.

 

Technical specifications:

 

  • decoupling nut consisting of nut and washer
  • selflock thread
  • serration
  • prevailing torque feature
  • special surface

 

The decoupling nut is used in exhaust application areas; It fixes the exhaust manifold to the cylinder head. The part can be applied in the areas of thermal and dynamic loads. As well as, in the areas of exhaust system where applicable.

 

By using this decoupling nut, thermal expansion, transverse displacement and mechanical vibration are not being transferred to the nut. Also, the usual loss of preload can be reduced and transverse displacement of up to + /-2mm can be realized.
