Drive Rivets

Blind Rivet Material Combinations

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 A4 Rivets – 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.

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.

Hammer Drive Rivet Type U

This rivet is formed in one piece and consists of a body having a helical thread, performing a deformation in the support where it is introduced. The visible round head secures relatively thin parts in all support.

U-drive rivets (also known as hammer drive screws or ) are unslotted round head self tapping rivets often used for attaching nameplates in castings and for sealing drain holes in corrosion proofing tubular structures.
They possess multiple start threads with large helical angles and an unthreaded pilot point.

Similar to nails they are driven into mating parts with a mallet or hammer for a quick and permanent assembly. No tapped threads are required in the mating part.

However, the u-drive screw must be of harder material than the
mating part and a undersized pre-drilled pilot hole is required.

The assembly can be done in a blind hole.

Drilling support and drilling piece to be fixed. The assembly is done manually with traditional tools (hammer, mallet or small hand press).

Used a lot for name plate of label fixing on metal bodies. That is why they are also known as name plate rivets.

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 Rivets	YES	CARE	NO	NO	NO
Coated Steel Rivets	NO	YES	NO	NO	NO
Stainless Steel Rivets	CARE	CARE	YES	YES	YES
Copper Rivets	NO	NO	YES	YES	YES
Monel Rivets	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
