Few things end a session faster than a fin screw you cannot shift on the beach, or one that has quietly rusted solid over winter. These replacement fin screws are machined from 316 stainless steel - the marine grade - so salt water is far less likely to leave you wrestling with corroded threads. The wide top head is shaped for grip, letting you fit and remove fins entirely by hand. No key, no screwdriver, nothing extra to lose in the sand. The M4 thread suits most standard longboards and stand-up paddleboards, including inflatables with slide-in single fins. Choose a pack of three or six; the spares weigh next to nothing in a board bag. Check your board takes an M4 fin screw before ordering.
