How do I know what type of wingscrews to order?
Most hydrofoils currently use either M6 or M8 screws to attach the mast to the board, these are 6mm and 8mm in diameter respectively. Then, there are two types of screws in each of these sizes...flat head (countersunk) or button head. To measure the length of a flat head screw, measure the complete length, including the head. For a button head screw, measure the length from under the head only. It is recommended that you measure the screws you are currently using prior to ordering. If your mast has a sloped base (Unifoil Katana, Cabrinha, Takuma M8 carbon, new Takuma aluminum, Cloud 9, etc.), you may need the tapered style wingscrews. There really are no "standard" length screws because there are so many variations in equipment. Our wingscrews are designated as the size of screw they are designed to replace. The picture shown on the product page is the actual item listed. If you are unsure about what to order, please contact us and we will be happy to help.
I ordered the wrong item...can I exchange it?
Yes, it is possible to exchange or return an item. However, the item needs to be unused with no visible wear or scratches. You will have to pay for shipping to return the item and then again to ship the replacement item to you. That means paying for shipping 3 times over so PLEASE contact me prior to ordering if there is any doubt about what you need!
What are wingscrews used for?
Wingscrews are designed to allow easy adjustment of your hydrofoil mast position while out in the water without the use of any tools. This can be very useful when setting up new gear or after making changes to your foil setup. Please do not use any tools to tighten your wingscrews or they could be damaged. Our wingscrews are wider than most typical hardware store wingscrews or wingnuts so allow an average person enough leverage to tighten them properly.
Why don't my wingscrews align with the centerline of my mast, i.e. in line with the water flow?
Our wingscrews are really just like any type of ordinary screw...the position in which they end up when tightened is completely random. Please do not use any tools to tighten your wingscrews! This may damage them and this type of damage is not covered under warranty. It is likely possible to improve the wingscrew alignment by swapping them amongst the 4 positions on the mast and/or swapping them over to different t-nuts, however, perfect alignment on all 4 screws is highly unlikely. Our product testers and some of our first customers say they haven't noticed any increase in drag while paddling. Once off the water, drag created by the wingscrews shouldn't be an issue for most.
Can you make a custom wingscrew not listed on your website?
Yes, it is possible to get custom wingscrews. It may take some time (1-3 weeks is typical), but custom wingscrews can be ordered for no additional charge.
How much is shipping?
Shipping for 1 or 2 sets of wingscrews anywhere in the USA is $6. Three or more sets can be shipped for $9.
Currently, we do not ship to Japan. Our Japanese distributor is On's Company and they can fulfill orders from within the country.
International shipping rates are automatically calculated depending on weight and location. If you are unable to get a shipping quote for your country, please contact us. It is likely possible to ship to most countries, but this may have to be done manually. Also, please contact us for international shipments prior to ordering as it may be possible to ship for a lower price...no promises, but we'll try.
How do I care for my wingscrews?
Saltwater is very corrosive so, if used in the ocean, it would be a good idea to rinse your wingscrews with fresh water after every use. Even after doing so, the aluminum will quickly tarnish but this should not affect the strength or function of your wingscrews. It is very important to not use any tools to tighten your wingscrews as this could damage them. If you have your setup dialed in, it really is not necessary to continue to use your wingscrews on a daily basis. We suggest you remove them, rinse well, and save for the next time you make a change to your foil setup.
What are your wingscrews made from?
Our wingscrews are made from aluminum and stainless steel. The wingnut portion is CNC machined from 6061 aluminum. The screw is stainless steel, usually either 18-8 or 316 alloy. The two parts are bonded together with a high strength retaining compound so they function as a single unit.
What is your warranty policy?
We want you to be happy with your purchase. Provided you do not use any tools to tighten your wingscrews, we will repair or replace any damaged wingscrews for a period of 6 months from date of purchase. We are continually trying to improve our products so if you manage to damage one, please send us a picture. Be advised that saltwater will tarnish metal and this is not covered under warranty.
