CELOPLAST screws

ZOOM

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 by a combination of technical features specifically designed for plastic assemblies.

CELOPLAST

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

CELOPLAST screws are being replaced by the new CELOspArk® offering an improved screw performance in the assembly of ductile plastics.

CELOPLAST screw benefits

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.
