Observation

The application is in plastics, in a humid environment. The customer wants to assemble a component with 2 different types of bolts: a very long and a shorter one. We can only offer one blind rivet nut fit for both bolt lengths to avoid mistakes in production. It has to become an extremely long closed end Tubtara® adapted to the length of the largest bolt. The customer also requires an increased torque-to-turn value.
