EJOT’s advanced fastening systems are found in countless industrial and engineering assemblies around the world. Click below for sales and technical support from one of our experienced team. We conduct inspections and observations onsite, in addition to providing help and advice direct from our UK manufacturing centre.

The ‘all-rounder’ for plastic assembly

The EJOT DELTA PT® screw is a special fastening element designed for reliable and easy direct assembly into thermoplastics. Its optimum design is the result of a long-term R&D programme in combination with experience of using DELTA PT® in the field for the direct assembly of even highly loaded thermoplastic materials. It has a wide range of possible uses, including all kinds of industrial applications, but it is in the automotive industry where the DELTA PT® screw has established itself as a dependable solution. This is through a design able to accommodate the very high loads which components used in automotive applications often have to withstand.

Individual design engineering assistance

To help achieve the ideal assembly, EJOT provides a valuable online prognosis programme to assist designers – the EJOT® DELTA CALC. This programme has been developed using data on the mechanical parameters of many thousands of applications and test assemblies, making it extremely useful for the pre-dimensioning of direct assembly into thermoplastics. Stored within the tool are the fastening parameters of the DELTA PT® screw according to material and pilot hole dimension, which helps designers save time during the design stage of a component.

Innovative thread geometry

One of the most important factors in the performance reliability of the EJOT DELTA PT® is its special thread geometry. This was developed by closely analysing the material displacement during thread-forming. The result is a flank angle which reduces the radial stress compared to common thread flanks with 60° angles. The respective 20° or 30° angles of DELTA PT® generate only slight radial stress enabling a thin-walled design to be realised. The thread flank also guarantees optimum material flow of the formed plastic even with reinforced thermoplastic. The ideal pitch of the DELTA PT® screw was determined by the balanced ratio of highest possible clamp load and low surface pressure in the plastic, which achieves very high thread engagement even at small installation depths.
