DIY Fin Screw Keychain

I lost one of my good Proteck fins the other day. Not because I was busting air, or shredding, or shralping, etc. I had a screw loose in my Future mount and it dropped off. I stink at surfing so much I didn’t even notice.
I guess this is a good time to argue at length about FCS and Future mounts- which is better?- but for now, I’ll just sit and cry. It was a good fin, and will be missed.
On the positive side, this made me think about holding extra screws just in case I ever catch one out before the fall. I know FCS makes a nifty screw and key holder keychain, but it’s a little bulky, and I usually carry a multi size Allen wrench tool anyway since I use a larger one for my SUP. The downside is too, that they don’t make these for Futures, as I’m aware.
So, I went to my go to- plastic modeling clay. It does anything and costs a buck a bar.

It’s not a turd, just brown clay.

I started by measuring my fin screws. The FCS screws are a little shorter than the Futures screws, so I need to take those measurements in consideration when making the thickness of my holder:

Next, I rolled off about 1/2 a bar of the clay, and rolled it until smooth into a ball. Then, I used a Plexiglas roller (or you can use your palm) to press it flat into a disc, or any shape you want, as long as it’s thicker than the fin screw type you’re using. Next, I took a screw (FCS in this case) and carefully “screwed” it into the clay with a key. Stay even and as straight as possible. You are creating threads in the clay to hold the screw in, so don’t make a lot of slop:

It’s like a fin screw donut.

I screwed the rest of the screws I wanted it to hold into the disc, being careful not to screw too far in and pierce the back of the disc.

After I had all the screws set where I wanted, and left IN PLACE (important!), I made a hang hole with a straw:

Next, leaving the screws in the clay, I baked this clay (FIMO soft) at 250 degrees F for 40 minutes to ensure hardness. I placed it on a cookie sheet on a piece of brown bag paper for the oven:

Ready for the oven!

After removing the screw holder and letting it cool, I made sure the internal threads were set by using my fin key to back the screws out of the holder:


After screwing the screw back into the holder, I attached the holder to a key chain with the fin key (if you need one), and marked the back in Sharpie marker “FCS” to indicate the type of screws in the holder.
Here’s the finished product:

You can use a less obnoxious sized key chain, but you can see that I can hold more screws in this little 1″ diameter disc, instead of just the two in the commercial one, and you can still put the key on your ring without as much bulk as the other, plus now you can put Future screws in one you make yourself!
Now I just need to improve my fin installation technique. I least I have them pointing the right way in the box- that’s something, right?
