The JP Australia M6 fin screw with PH3 head is a reliable fixing element used in windsurf boards. Made of marine-grade stainless steel, it offers good resistance to saltwater and intensive use. The M6 thread fits most standard fin boxes found in JP boards and many other brands.
Each screw comes with two washers – one rubber and one metal – to improve fit, reduce vibrations and increase durability. The PH3 (Phillips #3) drive allows for quick and easy installation using a standard crosshead screwdriver.
The length of each screw corresponds to the last digits of the SKU – for example, JP-242083_045 = 45 mm. Make sure to select the right length depending on your board and fin box depth.
