The Avibulb® rivet is a high strength, non-structural breakstem fastener. Steel is the only material choice, but it's available in a variety of sizes from 1/8" to 3/16" including an M6 diameter. Its all steel construction gives the rivet a surprisingly high shear strength, but it's a combination of excellent bulbing tail formation and radial expansion of the rivet body into the application hole that allows the Avibulb® rivet to create an extremely strong joint. 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 completely 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. The bulbing and expansion characteristics can only be controlled over a narrow range of material thickness and hole diameter. Therefore, the application hole size and grip range must meet the specified ranges to ensure proper installation and performance of the Avibulb® rivet.
