FIN SCREWS (Rigid)

Lost a fin screw or need replacements for your rigid paddleboard?

This set includes 2 screws and 2 square washer plates designed for rigid paddleboards and surfboards with US fin boxes. These are the standard screws that secure your fins—small parts that are easy to lose but essential for keeping your fins attached.

Why You Need These

• 2 screws and 2 washers included so you get a complete set for replacing lost hardware or having spares on hand.
• Designed for rigid boards (not inflatable) with standard US fin box systems found on most paddleboards and surfboards.
• Square washer plates distribute pressure evenly and prevent the screw from pulling through the fin material.
• Essential replacement part because these screws are tiny, easy to drop, and impossible to paddle without.
• Keep spares in your gear bag because losing a fin screw at the beach means you're not paddling that day.

The Essential Spare

Fin screws are one of those things you don't think about until you lose one. They're small, they fall out of pockets, they roll into cracks, and suddenly you're at the beach with a fin that won't stay attached to your board.

These are standard screws for rigid paddleboards and surfboards with US fin boxes. If your board has a fin box with a screw-in system (not the thumbscrew system used on inflatables), these will work.

The square washer plates are important. They spread the load across the fin material so the screw doesn't pull through or damage the fin. Without the washer, you risk cracking your fin or having the screw fail.

Getting a 2-pack means you have replacements ready. Keep one set in your gear bag, one in your car, or use both if you've lost multiple screws. At $14.95, it's cheap insurance against being stuck on the beach with a loose fin.

Common Questions

Will these fit my rigid paddleboard?
If your board has a US fin box system with screw-in fins (not thumbscrews), yes. This is the standard system on most rigid SUPs and surfboards.

Are these for inflatable or rigid boards?
Rigid boards only. Inflatable boards use thumbscrews, which are different. These are standard screws for rigid board fin boxes.

Why do I need the washer plates?
The square washers distribute pressure and prevent the screw from pulling through the fin material. Without them, you risk damaging your fin or having the screw fail.

How many fins will this cover?
This 2-pack covers 2 fins. Most boards have 1-3 fins, so you might need multiple packs depending on how many screws you've lost.

Can I use these on surfboards?
Yeah, they work on surfboards with US fin boxes. Same screw system as rigid paddleboards.
