The Avdel Rivscrew® Speed Fastening® system is a threaded, removable speed fastener that combines the speed of rivet placement with the benefits of being able to remove and re-fasten. Using a Rivscrew rivet removes the need for costly tapping or thread forming operation whilst creating a higher vibration resistant ‘thread lock’ compared to standard screws.
