Henrob Self-Pierce Riveting is a process that joins materials without pre-drilled holes by driving an engineered rivet into a material stack that pierces the top layers and flares into the bottom layer, forming a strong and secure joint. For over 20 years, Henrob has provided joining technology using this process for automotive and construction applications worldwide.
