Blind Rivets, Standard Closed End
Cost is a major reason why a manufacturer might choose to use a blind rivet in an application. The unit cost of blind rivets is much lower than the cost of most other types of fasteners. The labor cost savings is equally impressive, because they can be installed at a rate of up to 15 rivets per minute. Try matching that speed with a nut/bolt installation!
The typical governing factors in rivet material selection are strength, corrosion resistance and the material to be fastened.
Galvanic corrosion, also called “dissimilar metal corrosion” refers to corrosion damage induced when two dissimilar materials are coupled in a corrosive electrolyte (e.g. water). Certain materials should never be in direct contact with one another (like copper and aluminum), because a galvanic action will corrode one metal at a faster rate than the other. Galvanic corrosion is of particular concern in applications that are high in moisture content, like air conditioning and marine applications.
To assist in corrosion prevention, these rivets have a completely closed end to prevent the entry of liquids, moisture, air and other contaminants into the rivet or the riveted hole. Likewise, this rivet can be used to prevent the leakage of such materials from an assembly (e.g. fluid from a reservoir).
