Bulge Control Technology

BCT Concept

BCT is a new construction of Rivet Nuts. With four cross holes on the shank we can control where the bulge starts forming.


The Controlled Bulge insures optimal fitting  even into holes not perfectly round or irregular or oversized. For example in repair and maintenance work. The position of these cross holes and the dimensions of the product lead to different types of BCT Rivet Nuts

Up till now we found three different BCT products:


BCT Multigrip >>

High Tensile 12.9 >>
