Fasteners: Breakstem RivetsAvibulb® XT (Structural) - Dome Head
Description 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 multi-grip capability, especially suited for applications with varying sheet thicknesses. They also have the advantage of good hole fill compensating for irregular, oversized or misaligned holes.
As a multi-grip fastener, the Avibulb® XT rivet has the capability to join component parts having a broad range of thicknesses, thus reducing inventory where a variety of rivet sizes might otherwise be necessary.
During the rivet placing sequence the tail of the rivet body collapses into
a bulb shape against the rear sheet. This creates a load bearing surface,
which absorbs the force of setting the rivet. Otherwise the setting force,
or clamp load, could spread into the application material and might damage
the material. This makes Avibulb® ideal for use in thin sheet, soft,
brittle and low strength materials, as well as resulting in high resistance
to pull-out loads. Also during installation, the portion of the rivet body
contained within the application thickness expands outwardly toward the wall
of the application hole until the hole is completley filled by the rivet
material. This radial expansion results in a strong, vibration resistant
joint and compensates for irregular, oversized, slotted or misaligned holes.
Also, it can stop sheet movement in applications with non-standard holes
