摘要: In this fastening system two or more layers of material are fastened together by inserting a hollow sleeved fastener such as rivet bolt into the hole in high interference fit to expand radially. The sleeve is configured either collar and straight shank an angled upper portion combined with for counterbored applications. intersections between angle staight designed enlarged radius that when expanded after insertion inside it, expanded, which turn stress coins adjacent edge layers. This localized coining well hoop surrounding dramatically increases fatigue strength structure assembly.
