Fin screw with washer JP-Australia for inflatable SUP boards

Stainless steel screw designed for mounting fins in inflatable SUP boards from JP Australia. Compatible with metal-threaded fin boxes used in models such as AllroundAir, CruisAir, WindsupAir, and Venus. The screw comes with a small washer that helps prevent loosening during use. In these boards, the screw is inserted directly into the fin box thread without the need for a traditional sliding nut (as used in standard US Box systems). Not compatible with models like SportAir, which require a classic brass sliding nut – even though they also use the US Box system. Length: 16 mm Set includes: screw + washer Material: stainless steel
