Overview
Choosing the right rivet size is crucial for a strong, lasting joint. The diameter should be large enough to handle the load, while the length must be sufficient to form a proper head on the back side.
💡
Pro Tips
Always drill a hole slightly larger (approx 0.1mm to 0.5mm) than the rivet diameter.
Deburr the holes before riveting to ensure a tight fit between layers.
For best results, use a rivet material that matches the sheets being joined to prevent galvanic corrosion.

Fun Facts
"The 'grip range' of a rivet is the total thickness of the materials being joined."
"If a rivet is too long, it may bend instead of shortening to form a head."
"Aerospace standards often use 'Unwin's formula' for structural rivet sizing."
