Delta PT® is a thread-forming screw for a wide range of thermoplastics. It is engineered to create optimal material flow during installation, resulting in better clamp loads and increased joint life.
The Delta PT® trademark is registered and licensed by EJOT Holding GmbH & Co. KG
The unique flank geometry is designed to reduce radial stress on the boss compared to typical 60°flank angles
The multi-angled thread profile and unique cored recess provides maximum engagement by following the natural flow of the boss material.
Designed with a large bearing surface and a deep drive recess penetration to improve serviceability.
The increased minor diameter and larger cross sectional area offer an increase in torsional and tensile strength of up to 50% over the previous generation PT®.
The helix angle was developed by to resist vibration by optimizing the highest possible clamp load at low contact pressure in the plastic material.
