The EJOT® Delta PT is a screw specifically developed for thermoplastics. Thanks to its special thread geometry, the Delta PT® is a robust fastener that creates secure connections even in difficult constructions and operating conditions. It’s an ideal solution for lightweight applications.  

Benefits of Delta PT® Screws

Benefits

Ideal Material Flow

Delta PT® screws have a narrow thread flank geometry, which causes minimal radial stress. 

Benefits

This allows for an unimpeded material flow during installation and reduces potential damage to the head. 

Benefits

50% Higher

torsion and tensile strength.

Benefits

The Delta PT®’s V-shaped stress area can support a 50% higher torsional and tensile strength, even with a smaller thread pitch and shorter length. 

Benefits

Anti-Loosening 

and superior vibration resistance. 

Benefits

The thread pitch design ensures a high clamping load, which is crucial to reducing surface pressures and preload loss. This also improves the durability of the connection.

Calculate the Performance of Delta PT® Screws for Your Application

The DELTA® CALC calculation program simulates and predicts how the screw will perform in a given plastic. It also makes qualitative statements about the behavior of the connection under both static and dynamic loads. This enables you to see how safe and reliable the connection will be.  

Using your original components, we can determine the real values and details of the assembly parameters in our application technology lab at Bossard. Please contact us for your request.
