CELOPLAST screws provide higher pull-out resistance, improve ergonomics and avoid deformation of plastic bosses, greatly enhancing the technical properties of self-tapping screws. These advantages are obtained thanks to a combination of technical features specifically designed for fixing plastic.


CELOPLAST screw is recommended for assemblies in thermoplastics materials with a bending modulus between 500 and 30.000 kg/cm2.

Advantages of CELOPLAST screw.

• Less radial tension on plastic. It allows for bosses with smaller diameter and reduces the problem of boss bursting.

• Quick alignment of the screw before fixing, thus reducing assembly time.

• Lower thread forming torque, which offers 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 increase of surface contact between threads and nut member improves vibration loosening resistance.

• Possibility to reuse the screw, reducing the risk of stripping.

All of these advantages directly translate into a more resistant assembly, greater safety during threading and lower costs in assembly process.
