Countersunk Head Rivet

A countersunk head rivet is a solid rivet with a flat, angled head that sits flush with the surface once set. It joins two plates or sheets where a smooth face is wanted.

A countersunk head rivet sits flush in a countersunk hole. It joins metal sheets and other thin parts where a flat surface is needed. The rivet is set with a hammer or a rivet gun, and the tail is upset to clamp the parts.

Solid rivets are usually made of steel, aluminium or copper, and the choice affects strength and corrosion resistance. Aluminium suits light work and copper suits electrical and marine work.

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 report. On receipt, check the head angle is true, the shank is straight and the metal is free of laps or cracks.
