3.2MM 4MM 4.8MM BLACK POP RIVETS ALUMINIUM BODY STEEL MANDREL OPEN END DOME HEAD 

Pop Rivets ensure undoubtedly secure joints into a permanent mechanical fastening. Blind rivets are easy to install into a pre-drilled hole where they expand and create a secure and solid permanent fixing, making it idyllic for applications where only one side is accessible. The integration of the aluminium and steel rivet design guaranteed weatherproofing and corrosion resistance for a persistent life with optimum fastening performance.
