I need the screw knobs for the Thule cascade that fits the U bolts. It seems to be an odd thread size.

Hello Kevin. The Thule Cascade Cargo Box has been discontinued for quite some time, so that specific knob is not available. What you can do it use the Replacement QM3 - Quick Mount Hardware # TH04997 which will completely replace the mounting hardware (including knobs) for your Cascade cargo box. This will be the only option since parts specifically for the Cascade are no longer being made.
