Blind Rivet Terms
GOEBEL BLIND RIVETS
To join two pieces of material, the body of the rivet is inserted into a pre-drilled hole, then a nail rivet tool is used to pull the top of the mandrel to expand the body, clamping the two materials together. The force of the rivet tool then pops off the mandrel, leaving behind the domed head blind rivet.
Standard blind rivets can be placed on components that are accessible on one side or on two sides.
Applications: Containers/tanks, hollow body, tubes, profiles, air ducts and many others.
Characteristics: Economical • versatile • strong • secure
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.
|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
Types of Blind Rivets.
Open End “STANDARD”
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.
- Dome Head
- The Dome Headed or sometimes called Round head blind rivet is the most versatile and commonly used type whose lower profile head is approx. twice the diameter of the rivet body. This provides adequate bearing surface for nearly all applications where metals are being joined.
