An innovative, lightweight insert alternative

The cost and weight reductions demanded in today’s designs often require alternative approaches to common fastening requirements – and that includes joints that require inserts. To this day, many of the inserts used for numerous different applications indirectly fasten components using a costly post-moulded insert and a metric screw. This is a laborious method which EJOT has addressed with the development of an alternative insert – the aluminium EJOT DELTAsert®. This enables a reliable self-tapping assembly into highly loaded thermoplastic components, which was previously only achievable using pre or post moulded inserts.

Achieving a stable fastening point in plastic using plastic

To achieve a stable fastening point, the material strength of components made of thermoplastics is often insufficient. Even optimisations, such as a larger screw diameter, wall thickness increase or increased installation depth, are only partially suited to solving this problem. It is here where a special version of DELTAsert® provides the solution. For these difficult conditions EJOT has developed the innovative plastic insert solution DELTAsert® P which, combined with the EJOT DELTA PT® screw, facilitates process reliable fastening.

Easy installation

The EJOT DELTAsert® is screwed into the prepared plastic component with a conventional screw driver with torque limiter – additional controls are not necessary. The torque can be documented with the assembly unit. This process is finished in ca. 2 seconds. The subsequent assembly of the clamping part to the DELTAsert® with the EJOT ALtracs® Plus 60 screw is also self-tapping. For the version which uses a metric M6 internal thread, a metric screw can also be used as an alternative. An easy and process reliable assembly is guaranteed in both cases.
