Closed End Blind Rivets

Closed-End Rivets differ from a standard blind pop rivet due to their closed end, which creates a watertight seal. Closed-end rivets are used to attach materials quickly and efficiently. These rivets also boast a higher tensile strength than regular pop rivets.

Closed-End Pop Rivets are often referred to as sealed blind rivets or sealing rivets because they create a watertight seal when appropriately installed. This makes them a popular item in the boating and automotive industries. Closed-end pop rivets also provide complete mandrel retention, giving the sealed rivet a higher tensile strength crucial in electronic and electrical applications.

Blind rivets, also called "POP Rivets" after the brand that popularized them, have a two-piece construction; the rivet hat and the mandrel. Both the hat and mandrel are pre-assembled and ready to use. They are installed using a riveting tool to draw the mandrel, which causes the body to deform and clamp down on the workpieces, bringing them together. Upon reaching the designed clamping force, the mandrel snaps and is discarded.

Rivets are measured in installed grip range and length. The Rivet size guide above can assist you in finding the right size rivets for your application. For more information on rivet sizing and blind rivets in general, visit our Fasteners 101 page on the subject: Blind Rivets.
