Almost every foiler knows the problem: you just want to get on the water quickly, but - especially with foils where the screws cannot be inserted into the side of the mounting plate - you have to fumble the screws into the track nuts. Swiss wing pro Balz Müller was so annoyed by the fiddling before foiling that he immediately screwed the new product from manufacturer K4 Fins into his boards. In addition to the thread, a small Allen pin has been inserted into the small plates, which allows the plates to be easily fixed inside the double rail of the board.
So if you carefully loosen your foil during the first session - without the plates slipping - and then fix them in the appropriate position, all you have to do in future is put the foil on and screw it tight, eliminating the annoying shifting of the track nuts. The Locking T-Nuts are therefore particularly helpful for foils where the screws cannot be screwed into the side of the mounting plate. In addition, the favourite position of the foil is then saved, which can mean that you can enjoy the next session immediately and don't have to laboriously adjust the position of the foil again. The Locking T-Nuts are available in a set of 4 for both M6 and the thicker M8 screws for 25 euros in many surf shops. In addition to the Locking T-Nuts, there are other solutions that solve the same problem - you can find the links below.
