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
