Countersunk Blind Rivet

A countersunk blind rivet has a flush head and is set from one side. It is used where the outer surface must stay smooth.

A countersunk blind rivet joins sheets and panels from one side. It sets with a rivet tool, and the head sits flush with the top sheet. It often matches a hole with a matching countersink for a level finish.

This kind of rivet is often made in aluminium with a stainless steel mandrel, or in stainless steel throughout. Aluminium keeps weight down, while stainless steel gives better corrosion resistance.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and a material grade certificate. On receipt, check the head for correct angle and the body for cracks or deformation.
