Thread Rolling Checks/Verification

  • Thread rolling is a method for producing an external thread on a generally ductile material such as titanium, steel, aluminium or copper by forming the thread between rolls under high pressure.
  • The thread produced is generally stronger than the original base material, is uniform and produced to very tight tolerances.
  • The threads are normally rolled cold but can in certain circumstances be carried out at elevated temperatures.

Sectors using rolled threads include:

  • Aerospace
  • Nuclear
  • Automotive

The cold formed properties of the resulting thread include:

  • A precise smooth finish
  • Faster production method than thread cutting or grinding
  • Higher fatigue resistance
  • Higher thread strength
  • Higher shear strength
  • Higher thread repeatability
  • Lower costs per thread
  • Absence of defects causing by thread cutting such as tearing and chipping
  • No metal is lost during the process, saving wastage
  • Testing can be carried out to most international standards including specialised aerospace and defence related specifications.
  • UKAS and Nadcap accredited testing and certification, as well as specific aerospace approvals.
  • Full production or performance testing.
  • Testing may include the following:
  • Visual examination
  • Metallographic examination
  • Hardness testing
  • Shear testing
  • Tensile testing
  • Fatigue testing
  • Alpha case detection
  • All tests carried out on a single site

 Typical Specifications:

  • Airbus ABP 2-2333
  • British Aerospace R25-0498
  • BS EN ISO 898
  • BS A299, ISO 5857
  • Airbus AIPS 03-03-015
  • Rolls Royce RRES 90043
  • BS A 332:1999, ISO 9152:1998
