Specialty Blind Rivets
Blind Rivet Terms
Rivet Body
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.
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.
| METAL JOINED | |||||
| RIVET MATERIAL↓ | Aluminium | Coated Steel | Stainless Steel | Copper | Brass |
| Aluminium | YES | CARE | NO | NO | NO |
| Coated Steel | NO | YES | NO | NO | NO |
| Stainless Steel | CARE | CARE | YES | YES | YES |
| Copper | NO | NO | YES | YES | YES |
| Monel | NO | NO | YES | YES | YES |
| YES | Compatible | ||||
| NO | Incompatible – Avoid contact with each other | ||||
| CARE | Use with care. Painting metals will help | ||||
Hence,
1) Select materials that are as close together as possible in the Galvanic
Series Chart
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
mating material
SPECIALITY BLIND RIVETS
- GO PEEL Blind Rivets
- Peeled rivets are extremely versatile and necessary for joining softer materials without fracturing or distortions. These are particularly suitable for uneven surfaces or where oversized holes remain after repairs.
- Characteristics
- Fixing the rivet creates a closing head with a large diameter • after setting the mandrel head might remain within the rivet body or might drop out • especially suitable for connections with wood, hardboard, fibre-glass, plasterboard or similar • relatively soft or porous materials can be joined together with high tensile forces
- Applications
- Mounting of plastic, rubber, cardboard and felt elements etc.• mounting of wooden elements • construction of mobile homes • fixing of panelling and many others.

RILLI GROOVED BLIND RIVETS
The grooved blind rivet has been specially developed to attach hard materials to a fibrous substrate (e.g. wood or plastic) in situations where the hole does not go all the way through (blind hole) and the connection is established in the hole itself. The mandrel head is mechanically retained in the body. Perfect for combining metal with wood (flight cases).

Tre-Go Blind Rivets
The Tre-Go Blind Rivets are high strength rivets that are both vibration and weather proof through their fitted neoprene washer. Ideal for curved or uneven surfaces.
For a watertight joint. Especially suitable for roofing sheets.

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.
