OSI-Bolt Fastener

The revolutionary OSI-Bolt® is a direct replacement for solid shank pin and collar systems. The innovative design of this high strength fastener for primary structure delivers strength with the added advantages of simple one-sided installation and a flush break-off for installed cost savings in both metal and composite structure.
The updated titanium Ti-OSI® combines all these advantages in a weight saving configuration.
