The self-tapping screws that you are trying to wrap somewhere and strive to escape from your hands. Especially small ones. If you drop them, then you need to spend a moment to pick up the hardware. It seems to be easy. And if you work at a height, then going down for the screw will be lazy.
Sometimes you just don't pay attention to the loss, and you don't collect "kopecks". So precious (in fact, it is) material is lost.
I recently got a construction vacuum cleaner at my construction site KARCHER WD 3
Immediately I decided to apply the solution that took it into my head after losing a lot of small screws and nails when fixing the lining in the bath.
This upgrade will require a powerful magnet, preferably neodymium. We open the vacuum cleaner, we get to the bag.
Install a magnet at the outlet of the suction pipe. The body of my vacuum cleaner is made of magnetic stainless steel, so it was not difficult to fix it.
I assemble the vacuum cleaner in reverse order and begin to put things in order, suck in debris and dust.
At the end of cleaning, open the dust bag:
Voila, debris and dust fell into the bag. And valuable scrap metal, in the form of nails and screws, remained on the magnet. All that remains is to collect and return them to circulation. How do you like the idea?
