Modified slimmer design…V2. Slightly smaller 14mm diameter center section. Slimmer overall, but also smaller contact area between the wingnut and countersink in mast. The “wings” may sit lower on the mast plate so only recommended for mast plates that are flat. Not recommended for Cloud 9 carbon masts and possibly others. Please contact us before ordering if unsure.
Hydrofoil wingscrew set…designed for easy adjustment in the water without the use of any tools. One set of 4 wingscrews, equivalent to 25mm overall length M8 flat head countersunk screws. Machined 6061 aluminum and stainless steel screws. Fits Lift, Axis, some GoFoil and others. Most prone boards will use this size but please check your existing screws to be sure. Do not use any tools and do not over-tighten. Finger tight only. Do not expect the wingnuts to align with your mast.
