rivets

Shteinen rivets:

A rivet is a permanent mechanical fastener used to join two plates together. Because they’re permanent in nature, their joints are similar to those of adhesive or welded joints.

There are several different types of rivets, based on function, material, and shape. They include the standard solid/round head, semi-tubular, countersunk, blind, Oscar, drive, flush, friction-lock, and self-pierce.

The blind rivet, standard rivet and countersunk rivet, though, are the most popular types used today. The standard type is used when a smooth exterior isn’t necessary for aesthetics or on surfaces that won’t fit against another part. The countersunk type is used on flat surfaces where a smooth exterior is necessary. Finally, the blind rivet is used when you can only access one side of the plates being joined.
