Every master should have such a keychain.

Greetings to all self-made people on my channel. Today I present to your attention an interesting homemade product that every man should have in his pocket. A universal screwdriver is positioned by me as a keychain, or just a useful device that must be made and kept in the glove compartment of the car.

Manufacturing takes only 5 minutes and is notable for its simplicity. Start with 4 different beats. I chose flat, cross, hex and sprocket for myself.

Next, we take a bolt with an M6 nut and two metal washers.

Next, lay out 4 bits with a cross, as shown in the photo, close with a washer and tighten with a bolt and nut. Clamp as tight as possible. I admit, you will have to suffer a little with centering the bits, especially if you have thumbs or both hands are left)))

As a result, you should get such a homemade product.

It is better to fill the space between the bits with "Chinese snot" glue using a pistol. The presence of glue will significantly reduce the possibility of loosening of the bits during use and will prevent them from falling out if the nut looses.

This is how this keychain can be used in case of urgent need.

This is not the final version of the product. I wondered along the way, but you can take not 4 bits, but six or eight. Of course a wider washer would be required for that many bits. If you are the lucky owner of an automatic welding machine, then the bits can be welded to the washer for greater reliability.

That's all the homemade product. I look forward to your comments with suggestions and remarks.
