Blind rivets – rivet body – rivet stem or rivet mandrel. It is a type of rivet used for single-sided riveting, but requires the use of a specialized tool – a riveting gun (manual, electric, pneumatic) for riveting. During riveting, the rivet core is pulled by a specialized rivet gun, causing the rivet body to expand and play a role in riveting This type of rivet is particularly suitable for riveting situations where it is inconvenient to use ordinary rivets (which require riveting from both sides), so it is widely used in products such as construction, automobiles, ships, airplanes, machinery, electrical appliances, furniture, etc. Among them, open flat round head pop rivets are the most widely used, countersunk pop rivets are suitable for riveting applications that require smooth surfaces, and closed pop rivets are suitable for riveting applications that require high loads and certain sealing performance.

The existing types of pop rivets can be divided into two categories:
1. Ordinary open core rivets
Open type countersunk (flat head) core pulling rivet
2. Closed core rivets (also known as waterproof rivets)
deg flush head break mandrel closed end blind rivets
The main materials are aluminum, iron, stainless steel, and copper
3. Structural rivets
The biggest difference between structural rivets and ordinary rivets, apart from their high strength, is that the core of the rivet is locked in the rivet body without loosening after riveting Many people may think that the core of a regular rivet is still retained in the rivet body after riveting, but in fact, it is loose And structural rivets require a mandrel retention load
