Although blind rivets have been in use for numerous years, question still arise, from time to time, as to why they are used, the advantages and disadvantages of using them, and how to design and specify them, This article is intended to answer these question and to inform designers and engineers that blind rivets are one of the most cost effective, easiest methods of joining general application attachments on the market today. The rivet user is free from concerns, in his approach to his joint design, about space for holding tools, secondly parts (i.e., nuts, etc.), anti –rotation problems, and tool clearances. The rivet is installed from one side only, hence the name “blind.” There are rivet-like fasteners with locking rings with two-sided access required but these specials will not be discussed here in this general rivet article. They are special parts for special applications and the meat for another article.
