Forward-looking design for rivet nuts

BCT^® (see image) is the revolutionary design of rivet nuts. With four cross holes on the shank, we can control where the bulge starts forming in a range of materials from steel to composite materials. The controlled bulge ensures optimal fitting even into holes not perfectly round or irregular or oversized. The position of these cross holes and the dimensions of the product lead to different types of BCT^® Rivet nuts. The BCT^® has no radial expansion in to the sheet material reducing cracks or delamination. Additionally, this allows the BCT^® to be installed closer to the edge of a brittle profile. The BCT^® bulge will form where the holes are placed in accordance to the required material thickness. The BCT^® has approximately a 50% higher pullout force due to the full contact of the bulge on the sheet material and a higher quality of blind rivet nut material.
