Slingshot RapidTrack Flag Screw-M6 x 25mm

I have been using these for about 2 months now on my surf foil board and love it! I've always wanted a way to adjust my mast track position on my foil while in the water mid session and this is the answer. Especially when you are trying out new foil wings, you really do need to adjust your mast track position to dial it in to the correct spot. With these screws I'm able to adjust them on the fly in the water without any sort of tool. The spring loaded ratchet mechanism on them works really well and I haven't had any sort of issue with them corroding or with the mechanism not working, even in the sandy beach break conditions I am foiling in. Its also nice that they come with the counter sink washers which allows this M6 Flag Screw to seat properly onto a foil mast that is meant for an M8 screw. I've used this on my Armstrong Performance Masts as well as Lift Foils mast. 5/5 Stars!
