Includes: 4x Ti Screws with Alloy Handle (washers not included) North Hydro Thumbscrew Set Foil to Board Mounting 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. Features Ergonomic thumb and finger grip Micro-adjustable – after tightening screw lift and turn handle to align with the flow direction of the water Compatible with any foilboard using M8x30mm foil mounting screws Clean off any sand or dust particles and rinse screws with fresh water after each session. Dry thoroughly and spray beneath the handle with a marine lubricant to avoid galvanic corrosion.
