Specialist screw for lightweight thermosets

DELTA PT® DS supports the goal of using alternative materials to reduce weight in various types of industrial applications. Recent developments to use thermosets in place of other materials, particularly in the automotive sector where weight reduction of components reduces vehicle fuel consumption, have been facilitated through a new generation of screws like the DELTA PT® DS capable of meeting demanding performance criteria. Based on the proven DELTA PT® screw, it provides a reliable and durable connection of highly loaded components in even the most difficult self-tapping applications into thermosets due to its special thread layout.

Modified thread ends deliver superior strength

EJOT’s innovative DS (DuroSet) thread form holds the key to overcoming difficult fastening challenges in thermosets. It means the EJOT DELTA PT® DS screw features special grooves applied to the established DELTA PT® thread geometry, which enable optimal forming of the female thread. These grooves are pronounced at the screw point and taper off towards the screw head. This approach means the new zone for forming a thread enables a low installation and high stripping torque, and breaking of the screw boss can be effectively prevented with DELTA PT® DS. That is why this innovative screw is optimised for designs that make very high demands on the direct assembly process due to hardness and brittleness of the used material.
