Countersunk Rivet

Countersunk head rivets are installed into special recesses made in parts for this purpose. The design feature is that, once installed, the rivet is not visible above the surface of the part.

This forms a strong, permanent joint. These are typically thin-gauge metals, as well as facade panels fastened to a supporting substructure.

Applications

These types of rivets are widely used in machine and frame building. They are used on critical joints that must withstand vibration loads. Where a welded or threaded joint is not possible, countersunk head rivets are used.

Features

The materials used are carbon steel grades, aluminium, stainless steel and copper. Carbon steel is a strong material, while being inexpensive compared to non-ferrous and alloy materials. Carbon steel is often additionally zinc-plated. This protects the rivets from adverse environmental effects and corrosion.

An aluminium countersunk head rivet is an inexpensive, lightweight fastener with good performance characteristics.

More expensive versions are made of copper and stainless steel.
