Meet the EZ-NUT: the no-tools-needed screw for your single fin.
Anyone who’s ridden a single fin knows the pain of installing it. You dig through your tool box for a screwdriver, struggle to get the plate lined up with your fin, finally get your fin installed and decide to never move it again.
The EZ-NUT replaces the plate and screw system. It’s a tool-free fin screw built to fit any standard single fin box. Swap fins, adjust your position, or remove your fin for storage — all with your fingers, all in seconds.
Machined from marine grade stainless steel, the EZ-NUT is built to handle saltwater for a lifetime of surfing without rusting or seizing up.
Why surfers choose the EZ-NUT:
- Tool-free — hand-tighten and hand-loosen, no screwdriver required
- Fits any standard single fin box (not just longboards)
- 316 stainless steel (marine grade) — built for a lifetime in the ocean
- Swap or reposition your fin in seconds, wherever you are
Will the EZ-NUT fit my board?
If your board uses a standard single fin or center fin box with a plate-and-screw mounting system, the EZ-NUT fits. That covers the vast majority of longboards, mid-lengths, and single fin setups. If you're not sure, check your current fin setup — if it uses a flat plate that slides into the box and gets locked down with a screw, you're good to go.
Will my fin actually stay in? I don't want it coming loose in the water.
Yes — the EZ-NUT tightens hand-tight to the same holding strength as a screwdriver. We've never had a fin come loose. The whole point is to make installation easier, not weaker. Tighten it until it's snug, give your fin a wiggle, and if the nut's still tight you're done.
Does it work with my fin?
The EZ-NUT works with any fin that uses the plate-and-screw mounting system, regardless of brand.
Do I need any tools at all?
None. That's the whole point. No screwdriver, no fin key, no digging through your bag on the beach. Just hand-tighten and go.
What's it made of? Will it rust?
The EZ-NUT is made entirely of 316 (marine grade) stainless steel. It's built for a life in the ocean and won't rust.
