CELO, global industrial fasteners and screw manufacturer
For an optimal direct assembly of ductile plastics.
CELOspArk® screw is the last evolution of our CELOPLAST screw. The improved 30º thread design solves the problem of boss bursting and provides greater safety in the assembly process into ductile plastics.
When compared CELOspArk® to self-tapping screws (ISO 1478), the larger thread pitch and thread height of CELOspArk® screw results in bigger shearing zone, providing a more resistant nut member and, consequently, an increase in pull-out and stripping resistance.
If we carry out a resolution of resultant forces, 30º thread angle provides a 50% reduction of radial tension (Fr) when compared to self-tapping screws (60º).
The technical benefits of CELOspArk® screws provide a more resistant assembly, greater safety during threading and lower costs of assembly.
CELOspArk® screw is available in stock with the following designs:
To improve their functionality, CELOspArk® screws can be produced under different head types, recess, dimensions and coating configuration.
For further information on options available, please contact our applications engineers.
Recommended dimensions for hole diameter and length of engagement are available at DESIGN GUIDELINES.
The design of CELOspArk® screws meet the standards of a large number of electric material, electronics and automotive manufacturers (i.e. VW 603 62).
