The Surfboard Studio Spring-loaded Longboard Screw & Plate

The Surfboard Studio Spring-loaded Longboard Screw & Plate The spring‑loaded longboard centre fin screw & plate secures your longboard’s centre fin quickly and reliably - no fin key or screwdriver required. Made for standard sliding centre fin boxes, its spring tension locks the fin in place while letting you adjust or remove it in seconds, whether you’re in the water or on the beach. Perfect for longboarders, noseriders and travel surfers, the retainer stops fin rattle and loosening, removes the risk of lost screws, and is made from corrosion‑resistant materials for regular saltwater use. Use it to fine‑tune placement between sessions or to lock the fin down before a long paddle—secure hold with instant adjustability.
