A POP rivet (POP is a trademark of the inventor of the rivet, Tucker Fasteners Ltd (Birmingham), currently Emhart Teknologies) or blind rivet consists of the rivet body (bolt, hollow piece) and an elongated piece called a shank or pin (solid , inside the bolt). It is an artifact designed to firmly attach or hold pieces (mainly in sheet form) to each other.


Prior to the adoption of the blind rivet, the installation of a rivet typically required two people to assemble, one holding a rivet hammer on one side and a second person with a crash bar at the other end. Inventors like Carl Cherry and Lou Huck experimented with other techniques to expand solid rivets.

Other types

Unlike solid rivets, the pop rivet can be inserted at one end only by holding it by the stem and placing the head in the hole between the two surfaces to be joined (commonly plates or sheets).


The body of the rivet is manufactured by one of the following three methods:

  • Wire – most common method-
  • Tube – common in large sizes, not stronger than wire type.
  • Leaf – less popular, is the weakest option.

Blind rivets are widely used, when joining can be done on one side only. The head is placed in a predrilled hole in the parts to be joined and the stem is pulled so that it passes through the body of the rivet (head), so that it expands. As long as the head expands due to the sphere at the blind end of the stem, the grip becomes firmer; This can be done in several steps. At a certain moment, the stem reaches the breaking point, breaking and receiving a part of it in the body of the rivet.

This process requires a tool called pop riveting tool, which consists of a mechanical system that has treated steel jaws that, due to a combined movement of holding and pulling and subsequently advancing on the stem body freely in reverse, expand the rivet inside the hole. When the rivet shank breaks, it is housed in the rivet nozzle held by the jaws , and with the simple backward movement of the riveter handles, the shank is released.


The procedure is quick and simple, the force to fix it is determined by the design of the body and head of the rivet, the caliber and length of the parts to be joined or fastened. In some cases they are used on wood when an extraordinary bonding force is not required, -and in any case glue is used, achieving a better aesthetic effect-, they are also used on plastic in which it is not very common. Its use is widespread in the metal-mechanical area such as the automotive and aeronautical industries.
