A truss style rivet head features a low-profile, mushroom-shaped head with a large diameter. This shape distributes the load over a wider area, making it ideal for use with thin or brittle materials as it helps prevent the rivet from pulling through the material. It is often chosen when fastening soft materials to provide better support and to spread out the fastening force. The truss head is approximately twice the diameter of the rivet shaft and can be installed with a riveting hammer or special tools, depending on the rivet type (such as semi-tubular or solid rivets) .
Key characteristics:
-
Large diameter, low-profile mushroom shape
-
Distributes load over a wider surface area
-
Suitable for thin, brittle, or soft materials to avoid material damage
-
Commonly used in sheet metal fabrication, automotive, aerospace, and transport industries
-
Can be found in various materials like steel, aluminum, stainless steel
The truss head differs from other rivet heads like flat, round, pan, or countersunk by offering a broad bearing surface but not sitting flush with the material surface, providing strength without compromising delicate materials .
In summary, the truss rivet head style is designed to protect softer or thinner materials by spreading the load over a larger surface, reducing the risk of tearing or pull-through.
