Though they resemble solid rivets, semi tubular rivets are hollow at the shank end, forming a closed-end tube. They are installed by rolling the tubular end outward and over with a press and anvil. This action clinches the rivet into the material and fastens it in place. The fit can be kept tight to secure a joint or loose for hinged assemblies that require some length of the rivet shank to remain for the crimping process. This can be completed with a crimping die.
Semi tubular rivets are an economic choice of fastener and are suitable for use in settings that do not require a solid structural component. Only simple tools are needed for installation. They are an excellent fastener option when two materials need to be joined together at a low cost.
