Delta PT® screws have been developed to provide optimal material flow during installation of the screw into the thermoplastic material. 
This gives significant benefits over conventional thread forming screws such as increased clamp load, improved performance and increased joint life into a wide range of plastic materials.

Delta PT® screws are the latest development of the world leading PT® thread forming screw for plastic materials. This unique threadform has been designed and proven by Ejot in Germany, then manufactured under licence by Design Screws in the UK, ensuring we adhere to strict quality controls and Ejot licensee assessments. This level of support guarantees we produce a consistent high specification screw designed to provide optimum performance for your plastic joint assembly.
