Self-Piercing Rivets

National Rivet’s exceptionally strong self-piercing rivets surprise some people with their capabilities to fasten parts without the need for preformed holes.

Use self-piercing rivets to join similar or dissimilar materials, such as steel, stainless steel, aluminum, brass and certain plastics and fibers. Self-piercing rivets often provide the best fastening solution when spot welding is difficult or impossible, such as with zinc-coated steel (automotive, HVAC and building applications), pre-painted metal (white goods) and aluminum (signs).

Self-piercing rivets join two or more layers of material. The rivet first pierces the top layer of material. The anvil then upsets the rivet and causes it to flare within the bottom layer, thus forming a mechanical interlock.

Advantages Of Self-Piercing Rivets

National Rivet Advantages

With complete control over the design and manufacture of self-piercing rivets and rivet setting machines, National Rivet optimizes self-piercing riveting. For example, our in-house heat-treating capabilities assure consistent piercing and setting performance, while our stainless steel self-piercing rivets offer corrosion resistance. If you face accessibility issues, our custom anvil arms can reach into narrow openings. In fact, they can set a 1/8” rivet as close as 3/16” to a sidewall or flange.
