For applications with oversized or irregular holes, the Avdel Interlock® rivet can seal each hole with ease. Interlock® rivets are designed with an internal, mechanical locking component that can create a vibration-resistant and water-resistant seal. Because of its mechanical locking feature, the Avdel Interlock® rivet costs less to install compared to other locking mandrel rivets that are applied with special tools. One multi-grip Interlock® rivet can perform just as well as several standard grip rivets. Shop Bay Supply today for Interlock® rivets and other high-quality Avdel products!
