Rivets are an indispensable mechanical fastener for the construction of aircraft assemblies. Rivets feature a cylindrical shaft that has a head on one end and a tail on the other, providing the ability for the rivet to be passed through components before the tail end is made into another head. When the tail is formed into a head, the rivet then acts as a permanent fastener, supporting tension and shear loads without the risk of loosening. While solid rivets have proved their use since the Bronze Age, they always require access to both sides of a component for proper installation and head formation. This can create problems and consume time for aircraft assembly where accessing the other side of a component proves to be very difficult. Luckily, fasteners such as blind and pop rivets solve this problem by allowing installation from one side of the component. In this blog, we will discuss what blind and pop rivet parts are, and how they differ from each other.
