North Hydro Thumbscrew Set

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:

• 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.
