Industrial Fasteners


  • Secure and reliable direct assembly into thermoplastics
  • Light weight design: significant weight savings compared to screws made of steel
  • Reliable clamp load retention under thermal stress
  • No corrosion
  • Non-magnetic
  • Recyclable
  • Coefficient of expansion adapted to plastic

Innovative screw material

The trend subject "lightweight design" is one of the central starting points of cross-business research and development activities of many companies, in particular in the automotive industry. In the future special importance will be attached to the lightweight suitability of the used fasteners for applications in the field of direct assembly into thermoplastics. For that reason EJOT developed a DELTA PT® screw made of plastic, which fulfills these increased demands. This innovative fastening element made of the thermoplastic PPA GF50 with 50% fibre glass, offers the same joint reliability as metal screws but with a much higher potential for weight reduction. A plastic DELTA PT® P screw with similar dimensions weighs up to 85% less than its counterpart made of steel.
