Blind Rivet Terms
Aluminium – Lightweight with good corrosion resistance.
Steel – Stronger than Aluminium with a “flash” coating of Zinc. Low corrosion resistance.
Stainless Steel A2 – Good Strength and excellent corrosion resistance.
Stainless Steel A4 – Good Strength and increased corrosion resistance
Copper – Relatively soft. Excellent corrosion resistance and conductivity.
Monel – The strongest blind rivet material with excellent corrosion resistance and conductivity. Also excellent high temperature suitability.
HAMMER DRIVE Blind Rivets
The hammer drive blind rivet was specially designed for attachment of hard materials to solid wood and similar materials. As soon as the drive pin in the hammer drive blind rivet is struck, the end of the rivet splits into four sections that hold the materials together, while the borehole diameter is 0.5 mm greater than that of the rivet. Ideal for fixing profiles, insulation, etc, on construction materials. The rivets are set with a hammer or striking mechanism.

Material USAGE GUIDE.
Galvanic Corrosion • When dissimilar metals come into contact in the presence of an electrolyte, a galvanic action occurs which corrodes one metal at a faster rate and the other more slowly. This phenomenon can cause major riveted joint failures and care must be taken to avoid the occurrence. The following table is a guide.
|RIVET MATERIAL↓||Aluminium||Coated Steel||Stainless Steel||Copper||Brass|
|NO||Incompatible – Avoid contact with each other|
|CARE||Use with care. Painting metals will help|
1) Select materials that are as close together as possible in the Galvanic
2) Provide a barrier between the two metals, such as paint, non-metallic
washer or gaskets
3) Design the fastener as the cathode so the cathodic area is small as
compared to the anodic area
4) Use a metallic finish on the fastener that is close on the chart to the
