Fasteners - Breakstem Rivets Avinox® XT (Structural)
The new structural Avinox® XT breakstem rivet offers a high-strength fastening solution ideal for thin sheet metals. It provides excellent bulbing tail formation and high shear and tensile strength combined with multi-grip capability. This industrial fastener’s stainless steel construction provides good corrosion resistance in applications subject to elevated temperatures. As a multi-grip fastener, the Avinox® 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 Avinox® 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.
