Secure. Spare. Paddle On.
Nobody thinks about their rigid paddleboard fin screw until it's gone. One slips loose in the parking lot, rolls under a seat, and suddenly your fin won't stay put, and your session is over before it starts. The POP rigid SUP fin screw is a little set of replacement fin screws that is the quiet hero of your gear bag, the part that keeps your fin anchored to your rigid SUP or surfboard, so you can actually get on the water when you show up to ride.
Think of it as cheap insurance for every paddle day. Toss a set in your bag, leave one in the car, and you'll never be the person watching the waves with a wobbly fin. With the POP rigid SUP fin screw, you're trading a few dollars for the confidence that your US fin box stays locked, your fin stays protected, and your time on the water stays yours. Stock up once, and paddle on without a second thought.

Frequently Asked Questions
Will the POP rigid SUP fin screw fit my rigid paddleboard?
If your board has a US fin box system with screw-in fins (not thumbscrews), yes. This is the standard setup on most rigid SUPs and surfboards, so these screws should slot right in.
Are these for inflatable or rigid boards?
Rigid boards only. Inflatable boards use thumbscrews, which are a different system. These are standard screws designed specifically for rigid-board US 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 mid-session.
How many fins will this cover?
This 2-pack covers 2 fins. Most boards run 1–3 fins, so depending on how many screws you've lost, you may want more than one pack.
Can I use these on surfboards?
Yes, these POP rigid SUP fin screws work on surfboards with US fin boxes too. It's the same screw system used on rigid paddleboards.
