It is advisable to use nuts with a nylon insert to avoid self-loosening (although I doubt that this will happen).

You need a lot of vibrations for self-loosening a nut. From the tests I've seen, nylon inserts help a bit but given enough vibrations, it'll still get loose. None of this should be a problem for your seed word storage though, unless maybe if you store it on top of your car engine for years.

If the vibrations of the nuts cause a problem for someone, then you can use one trick: instead of one nut per bolt, tighten two nuts. You will be surprised to see how reliable it will be. Check this out for authenticity sometime.

Some thoughts about alternative versions of the Seed Phrase Washers prompted me to write this post.

Very nice.
In my opinion, washers are more ubiquitous than metal plates and may have a final form factor that is easier to conceal.
Yet, your solution is perfect, as it uses commonly available materials and preserves the holder's privacy.
Of course, the weakest link in my guide is the jig, which is necessary for my method, while you found an excellent alternative for those who haven't been able to find one.

Security models are very different as different attack vectors are possible: there isn't a "better solution" for everyone as scenarios are different for everybody. This guide is excellent for those who want to rely on pieces you can find in any hardware store.

.

I agree, the washers probably seem universal due to their form factor, but this also imposes some limitations. But there are still some advantages, one of which I wanted to highlight. This is an opportunity to enclose a stack of washers in a metal capsule tube to provide greater durability and protection from environmental influences, while at the same time providing some camouflage. Although a stack of bolted plates can be placed in a metal box, which will have similar characteristics.

I don't think plates are any harder to find than washers. Everything is publicly available. The choice between a washer or a plate will depend only on individual preferences. In general, systemically, both options are not very different from each other.

I wouldn't say there are perfect solutions. More like an alternative. As for jig, can do without it by showing resourcefulness or patience (without hand tremors

).

That’s right, it’s impossible to protect yourself from “all attack vectors” and have to try to protect yourself from the maximum possible for you.
