For sure it can! Absolutely. Been there, done that.

But is it worth taking a risk after all that DIY work? Some good builders here even TIG/MIG welded SS plate on the nut:) With 60-100$/per hour in AU for a good welder I would think twice :)

So whatever floats your boat, uhm board :)

They have a good collection of stainless inserts and are canadian.....Lowest prices I found for a bulk order i did

Pot them in cut outs >1" diameter if you ride hard.
Install in clusters or with a potted X to get some further hold for boots.

What you should look for is this :

The wide part of the nut is facing down to the board.

Have fun

Please use inserts with a closed solid base, with these types the bolt pierces the bottom of your board if they are the slightest bit too long.

This is the correct type to use that doesn't rotate inside your board:

SS 316?

Hardly. The thread on this inserts will corrode in no time, at least my did. Not to mention cutting this spikes.

The above are not bad, but you risk the air bubble trapped in a rounded hole drilled with a forstner bit. To minimise the risk of an air bubble the hole must be a tiny bit bigger than the insert. There is a video somewhere from a factory where they hammer the insert in, that's how tight that is. But, each to his own.

And at the and, inserts with no cap on top are bastards to with with...Good luck.

Well 316SS does in fact corrode. Now in normal conditions yes those inserts will not corrode. They are made for frozen fresh water. Even when if you use the ones for wake-boarding that is with fresh water in mind. Really the problem is the amount of SS they use since they are not a high grade of stainless the salt will eat them. I work in a chemical plant and salts are the worst when it comes to eating away at our equipment. I'm talking about high quality stainless too. But this is like comparing apples to a gourmet 7 course meal.

All so if you ever use a non SS screw or any tool of a non corrosive metal you will get corrosion on stainless. Sometimes it's not the stainless that is corroding but left over molecules of iron from contact. Learned all that back when I was young working in construction on some high grade piping with welders. If a grinding disk, or wire brush was used on anything but stainless it could not be use. It would cause a weld to fail inspection.
