Secret Keychain Safe Looks Just Like A Bolt

While conventional safes can be a good place to put valuables, sometimes it’s even better to hide your things where nobody will even look in the first place. [Wesley Treat] has a build that will allow you to do just that, which secrets away papers, money, or small items within the body of a bolt.

There’s a surprising amount of room inside.

The build starts in a proper hacker fashion, using a power drill to turn an aluminium blank against a power sander creating an ersatz lathing setup. The outside of the blank is then threaded with the aid of a socket wrench and die, to great success. A cavity is created inside and threaded internally, and a separate head is then machined to screw on top. It’s all achieved without the use of a real lathe, with [Wesley]’s power drill doing most of the heavy lifting instead. It’s great stuff.

The end result has the appearance of a socket-head cap screw, while being lighter than a typical example due to the aluminium construction. Inside, there’s room for money, matches, and more, and [Wesley] even put in a small hole so the bolt can be used as an attractive keychain.

It’s a neat build, and one that we’d love to have as part of our own everyday carry. Video after the break.
