North Hydro Thumbscrew Set 2026

Titanium screws with hydrodynamic alloy handle for fast foil-mounting and toolless adjustments on the go. Loosen the screws by hand to slide your mast forward or back in the DropBox track, then re-tighten by hand, lifting handle to orientate into flow direction of water. WARNING: Tighten by hand only. Do not use any tools, and do not over-tighten. Due to the reduced torque moment of the thumbscrews, they can loosen more easily. Check screw tightness before and during sessions.IMPORTANT: Rinse screws with fresh water after each session to remove any sand or dust particles. Dry thoroughly then spray with marine lubricant beneath handle to avoid galvanic corrosion. show less
