Surfboard Fin Fun: Hack Attack

Here’s a little hack attack to save some cash on what I consider to be a VERY handy item for single fins and longboards.

A typical single fin screw requires a flathead screwdriver or Phillips head to get out. What a pain in the ass.

Some time ago, a fin company carried a special “longboard fin screw” that was a thumbscrew, so you didn’t need the screwdriver. Also, you could move the fin in the box on the fly. Nice.

Problem was, they wanted $12 PER SCREW and NUT set. REALLY???? Screw you.

I’ve got a simple cure for that- buy it directly from a hardware store. I order what’s called a 316 Stainless Steel Thumbscrew. Stainless Steel is important for it to hold up in saltwater, yo:

Get the good stuff for saltwater

Here is a new one in 316 Stainless, next to another one that’s been surfed for about 8 months on the regular:

Not significant amount of rusting for so much use

I’ve found that the 8/32 thread size fits most single fin box  nuts that usually come with the fin, or also the surfboard itself. I only get the 3/4″ length to fit the depth of most single fin boxes.

Shareable Size

Here’s a link to the place where I got mine:

McMaster-Carr (I don’t get anything for this, it’s just a link to the page)

Remember how I said I wanted to move my fin to the back of the fin box? I used the nut I already had that was in the box, but I can just switch to this type of screw:

No screwdrivers!

Ready to go and secure

That’s it, Bro-licious. And they’re FIVE screws (no nuts included) for $6.50, plus shipping. Mark ’em up and sell them to your friends, or give them away and score some surf cred. They’re super mega handy, believe me.

And if you’re going to bitch about the thumbscrew affecting the flow of water over the foil of the fin, thus creating vortices of instability, well, “bless your heart.”
