Rivet Nuts, 3/8″-16 Carbon Steel Stainless Steel Unc Rivet Nut Assortment Kit, Flat Head Threaded Insert Nut

Rivet nuts, alternatively known as RIVNUT, also called blind rivet nuts or threaded inserts, rivet nuts are internally threaded components that are completely anchored on one side. Originally used to secure deicing boots to aircraft wings, rivet nuts have since been adapted into many different forms and types for various fastening applications.

Rivet nuts are derived from standard rivets and are paired with standard sized bolts. Rivet nuts can have round, square, splined, or hexagonal bodies. Because it’s considered a blind fastener, rivet nuts are used in applications where only a single side of the workpiece is accessible. This makes rivet nuts one of the most versatile fastening devices that exist.
Blind rivets, also commonly referred to as POP Rivets, are mainly used in applications where there is no access to the rear (blind side) of the joint. Rivets have a two-piece construction; one is called the rivet body, shell, or hat and another is called the stem or mandrel. Both the hat and mandrel are pre-assembled and ready to use. Rivets are installed by using a riveting tool to draw the mandrel which causes the body to deform and clamp down on the joint. Upon reaching the designed clamping force, the mandrel snaps and is discarded. A benefit of blind rivets is that they are not material specific meaning they can combine two different material types together the same way.
