Large Flange Blind Rivets
Open End “STANDARD” Blind Rivets
General purpose rivet available in a wide range of materials and head styles.
Suitable for applications with normal load bearing requirements.
By far the most commonly used style of blind rivet due to the ease of use and low initial cost.
Rivet Body
Aluminium Rivets – Lightweight with good corrosion resistance.
Steel Rivets – Stronger than Aluminium with a “flash” coating of Zinc. Low corrosion resistance.
Stainless Steel Rivets A2 – Good Strength and excellent corrosion resistance.
Stainless Steel Rivets A4 – Good Strength and increased corrosion resistance
Copper Rivets – Relatively soft. Excellent corrosion resistance and conductivity.
Monel Rivets – The strongest blind rivet material with excellent corrosion resistance and conductivity. Also excellent high temperature suitability.
Large Flange Rivets
The large flange blind rivets are very useful for joining low density materials.
In particular when the softer material is on the front side, the large flange spreads the load over a larger area and prevents the rivet from penetrating the material.
Available in many material combinations.

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.
