Hydro Thumbscrew Set
Foil to Board Mounting
Titanium screws with hydrodynamic handle design for quick foil mounting and tool-free adjustments on the go.
The screws can be loosened by hand to move the mast forward or backward in the DropBox track, and then tightened again by hand. The handle can be aligned with the flow direction.
Warning: Tighten by hand only. Do not use tools and do not overtighten. Due to the lower torque, screws can loosen more easily – check tightness before and during the session.
Important: Rinse screws with fresh water after each session to remove sand and dirt. Then dry thoroughly and treat under the handle with marine lubricant to prevent galvanic corrosion.
- Ergonomic thumb and finger grip
- Micro-adjustable – after tightening, lift and turn the grip to align it with the water flow direction

- Remove sand and dirt after each session and rinse the screws with fresh water
