Closed End Blind Rivet

A closed end blind rivet seals the tail after setting, so the mandrel is retained inside the body. This blocks water and air from passing through the hole.

A closed end blind rivet joins parts where a sealed hole is needed. It sets with a rivet tool, and the closed body keeps the mandrel from pushing through. It suits work where water or air must not pass through the joint.

This kind of rivet is often made in stainless steel, which gives good corrosion resistance in wet or coastal conditions. It can be used where mild steel would rust.

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 pressure or leak test report if the joint is critical. On receipt, check that the closed end is intact and the mandrel is not loose.
