5 Self – piercing rivet: Self-piercing rivets (SPRs) are a type of fastener specifically designed to join two or
more materials together without the need for pre-drilled holes. These rivets are commonly used in industries
such as automotive manufacturing, where they offer significant advantages in terms of efficiency, reliability,
and cost-effectiveness.
6 Threaded rivet: Threaded rivets, also known as threaded inserts or rivet nuts, are fasteners designed to
create a threaded hole in a material where it’s not feasible or desirable to tap threads directly. These rivets are
particularly useful for applications where a strong, reliable threaded connection is needed in thin or brittle
materials.
7 Semi- tubular rivet: Semi-tubular rivets, also known as tubular rivets, are fasteners with a hollow or partially
hollow shaft. These rivets are commonly used in applications where a strong, permanent joint is required, such
as in automotive, construction, and manufacturing industries.
