M4x23 US Box Fin Screw – A4 Stainless Steel
This premium M4 countersunk screw is specifically engineered for securing fins in the US Box system. Made from acid-resistant A4 stainless steel (AISI 316), it is fully marine-grade and protected against saltwater corrosion.

Application: US Box Fin Systems (Longboard, SUP, Windsurf)
Thread: M4 (metric)
Total Length: 23 mm (incl. head)
