This 5mm finger tighten center fin screw and plate set provides a simple, tool-free method for installing and adjusting a surfboard center fin. The screw features an enlarged, easy-grip head that allows firm hand tightening without the need for a fin key or screwdriver, while the matching metal plate delivers stable positioning inside the fin box channel.
