Surfing/How to Remove a Stripped Fin Screw/The cause may be that the corner of the fin-key was broken, not the hexagonal hole of the screw was crushed.

What’s up?

I have the same experience as you. The cause may be the finkey, not the screw.
This time, I will talk about what to do when the fins cannot be removed.

Let me tell you my case. I thought the cause was the hexagonal hole in the screw. I imagined that the hexagonal corners broke as I used the fins many times. Even if I stab a fin-key, it just spins idle. I bought a new screw.

That’s right. I thought the screw was the cause. Therefore, I thought that I needed to replace it with a new screw, so I bought it.

It was an amazing ending. I have multiple fin keys. However, I did not replace the fin key. I used the same fin key for a long time. I couldn’t remove the screw from the surfboard, so I casually tried using a new fin key. Then, I was able to easily remove the screw.

I compared the old fin key with the new fin key. The old fin key was broken because the hexagonal corners were worn out. That’s why it was spinning.

I imagined that the fin key material is probably less hard than the screw material.
Do you all have similar experiences? If you cannot remove the screw, first replace it with a new fin key.
