Reduced Shank Studs for Din Flanges


Manufacturing process:

  • Use of pre-heated steels
  • Thread rolling assuming fibred structure, profile compliance, surface quality, improved resistance to jamming corrosion and fatigue.
  • Fine machining of the elastic shank and radius
  • Hot-forged nuts, heat treated before tapping

 

Testing:

  • Product check analysis
  • Visual and dimensional examination
  • Metallurgical examination: tensile strength test, hardness tests, creep-rupture and stress-rapture test etc.
  • Non-destructive examinations.
