When to choose CELOPLAST screw?


  • Less radial tension of plastic. It allows for bosses with smaller diameter and reduces the problem of boss bursting.
  • Quick alignment of the screw before screwing in, thus reducing assembly time.
  • Lower thread forming torque, which provides a more ergonomic assembly.
  • More resistant to pull-out and stripping, which enables its use in assemblies with high pull-out resistance and/or compression requirements.
  • The increased contact surface between threads and nut member improves vibration loosening resistance.
  • Screws can be reused with a reduced risk of stripping.

All of these benefits together provide a more resistant assembly, greater safety during threading and lower costs of the assembly process.
