Monobolt

However, the main feature of the Avdel Monobolt® rivet is an internal, mechanical lock of the rivet stem. A special nose tip with a cutting ring (anvil) is required. During installation, when the mandrel head comes in contact with the nose tip, the anvil cuts into and folds material from the mandrel head (skive) into a ledge located in the inner diameter of the rivet head. This prevents the mandrel from falling back through the rivet. Additionally, the locked stem forms a weather tight seal and provides a very strong, vibration resistant joint without the damage, electrical problems or rattling due to loose stems.
