The tall self-aligning roll-in T-nut with spring leaf is a fastening option that loads either from the profile ends or side, which is helpful for applications where the ends are inaccessible. The projection on the T-nut aligns it in the T-slot while the spring leaf holds the fastener in place, even when the profile is in a vertical position. It is a strong and durable connection method that is available with different thread options.
