Although a traditional safe can be a good place to store valuables, sometimes it is best to hide your things in a place where no one will see it. [Wesley Treat] There is a build that allows you to do this. It hides files, money, or small items inside the bolt.

The construction starts with the proper hacking method, using an electric drill to face the aluminum blank against the electric sander to create an imitation lathe setup. Then with the help of a socket wrench and a mold, the outer part of the blank was screwed into the thread, which was a great success. Create a cavity inside and use threads inside, then machine a separate head to screw on the top. All this was achieved without using a real lathe, and [Wesley]’s electric drill replaced most of the heavy work. This is great stuff.

The end result has the appearance of a hexagon socket screw while being lighter than the typical example due to the aluminum structure. Inside, there is room for money, matches, etc. [Wesley] even put a small hole so that the bolt can be used as an attractive keychain.

This is a neat build, and we want to make it part of our own daily carrying. Video after the break.

I *just* bought *exactly the same thing* on AliExpress a few hours before seeing this article, what is the chance...

The plan is to hide a small/interesting/good news and a small candy on a piece of paper and use the bolt customers inside the 5-axis CNC milling machine/laser cutting machine combination I am currently completing.

So maybe sometime in a few decades, when someone disassembles or updates it, they will discover the secret and be happy about it, and I will make someone smile, far away, for a long time.

Oh, by the way, if anyone is curious, the AliExpress page: https://www.aliexpress.com/item/10000010892822.html

Wow, I just found the second one, its appearance/format is closer to the one in this article, it's crazy: https://www.aliexpress.com/item/1005001980234379.html

If you use it instead of regular bolts, please don't tighten them too tight, otherwise it may be difficult to disassemble :)

Oh, yes, thank you in fact, I will be very careful where I use it, maybe I should put it where I don’t actually need it.

If you place a hollow bolt with a screw-out head somewhere instead of an ordinary bolt, you'd better hope that the original bolt size is too high. It will definitely be interesting for future maintenance, but if the hollow bolt is cut or the head is loosened and the CNC fails, you may be liable because you know that a bolt that does not meet the specifications is used. Maybe stick it somewhere outside the work area instead of replacing real bolts.

I like the mood of this idea.

Another risk is that someone has performed some maintenance and reinstalled the "fake" bolt in a more critical location without realizing it has been damaged.

Maybe put some ball bearings in it to arouse suspicion and trigger investigation.

He looks like a mixture between Tom Green and red and green.

Haha, I only vaguely know who those two people are (musician and Canadian tape lover), but I completely see the similarities!

Before someone accidentally uses it to repair heavy machinery, it's all fun and games.

But there is a small hole on the top for the key ring. I suspect that someone will use it in machinery unless it is an apocalyptic scenario.

Unless they think it is used for winding.

Heavy-duty bolts used in the industry usually have holes in the head for thread locking.

But compared with this, steel bolts also have considerable weight. Oops, it doesn't even sound like ordinary steel bolts. Hollow aluminum bolts will almost certainly be noticed shortly after installation. This seems too obvious to be mistaken.

Don't forget that a bolt of such a size will have a considerable amount of torque during installation.

I would say it is hollow and aluminum, even if it is rotated by hand, the head will be cut off.

I wanted to say that it is best to cut it with some left-handed non-standard pitch thread, otherwise it may end up fixing the head somewhere in the engine block. Either way, some people will be upset

Using a left-hand thread, it can fix the head on Alfa Romeo.

JD Truby and J. Minnery describe some things that can be done with hollow bolts (in their book-no longer exists-Palladin Press).

Am I the only one who thinks it will benefit from some kind of actual "locking" rather than just a screw on the head? Make sure that if someone shouldn't discover its internal secrets to deal with it, then the sudden twist of the head relative to the body will not warn them that the bolt is abnormal this time? I'm not sure what kind of "lock" can have an invisible hidden keyhole to avoid the illusion of breaking ordinary bolts, but it is worth thinking about.

All about what you want it-maybe some kind of simple latch, or just a pin that locks the two together-the visibility of this mechanism is almost entirely the choice of the builder, how much internal A small group of them are willing to give up anything a little complicated.

I saw a similar project that uses nickel coins and a quarter that is ground out, so there is a small compartment, and when they have a seamless edge, it is a bit tricky to separate.

Oh man, I can hide something in there! I like it!
