The new Avdel Avibulb® XT is a high strength breakstem fastener with excellent bulbing tail formation, which makes it ideal for the use in thin sheet materials. Avibulb® XT structural fasteners feature a wide grip range, especially suited for applications with varying sheet thicknesses. They also have the advantage of good hole fill compensating for irregular, oversized or misaligned holes.
