How to make a self-tapping screw controllable and twist at any angle

This idea was suggested by my good friend who is engaged in roofing, where you constantly need to think about safety, then how with a screwdriver it is not always and not always possible to turn the screws with both hands, and sometimes it needs to be done under angle. Because of this, the head of the roofing screw may not hold on to the bit and pops out because of the backlash. Even when screwing the self-tapping screw at an angle, there is a possibility that the fasteners will slip, and then deep scratches remain in the metal tile or corrugated board.

So, in order to avoid any backlash when tightening and guaranteed to protect the self-tapping screw from jumping out and slipping off, the screwing attachment must be removed altogether!!! Yes Yes.

Self-tapping screw clamped in the chuck.

1) After that, it is necessary to dilute the clamping jaws as much as possible inside the self-clamping chuck. 2) Then bring the head of the self-tapping screw inward, sliding the washer with a sealing gasket just below the body of the self-tapping screw and 3) well clamp the hexagon of the self-tapping screw in the chuck.

So the roofing screw turns into an extension of the screwdriver and you can work with it anywhere and at any angle, without fear that it will fall out and fly away somewhere. And you can get by with the efforts of one hand.

And with a self-tapping screw fixed in this way, it is very convenient to drill holes in thin sheet metal. The thickness of the metal should not exceed the length of the drill at the tip of the self-tapping screw. Moreover, this even applies to roofing screws for wood. Here's a little trick for difficult situations. How do you like the idea?
