Blind rivets are a type of rivet used for single-sided riveting, but require the use of a specialized tool - a rivet gun (manual, electric, pneumatic) for 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 smoothness, and closed pop rivets are suitable for riveting applications that require higher loads and certain sealing performance.
