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

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

 

Head Styles.

 

 

 

 

 

 

 

 

  • 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.

 

  • CSK Head
  • The Countersunk or CSK head profile provides a neat and flush finish to the joint. This enables multiple layered assembly and also a safe surface without any projection.
  • LARGE FLANGE

 

CLOSED End “CUP”

Also known as Sealed Blind Rivet.

Designed with a completely closed body, this rivet is ideal for applications that need to be
water/pressure tight or where mandrel retention is paramount.

Used for providing a leak-proof joint.
