EFC International’s BCT Rivet nut, manufactured by BBA with BCT® (Bulge Control Technology), is pitched as a best practice light-weighting solution for attaching carbon fibre and composite panels in the automotive sector.
BCT Rivet Nuts are ultra-high strength and engineered to prevent cracking or delamination of carbon fiber panels.
The patented design enables an engineered yield point on the body of the rivet nut ensuring the bulge formation always begins beyond the panel and is drawn back on the panel. BCT rivet nuts can be placed near the edge of the panel without fear of inducing a crack in the panel, the brand said.
Process-monitoring
The installation process of BCT rivet nuts can be fully process-monitored and controlled.
They can be installed into areas that offer limited rear side clearance. An M6 rivet nut needs only 8mm of rear side clearance prior to installation and only 5mm after installation, ideal for use in thinner version of sandwich (composite) materials, avoiding the need for a through hole. The bulge of the BCT product is strong enough to form by pushing away any material in the sandwich material.
Additionally, BCT rivet nuts are produced from aluminum for use in aluminum and magnesium, drastically reducing weight.
