Screw/nut/bolt driver for pneumatic, impact, hand crank or other use having an insertable magnet in the head to hold/keep screw/nut/bolt or specialized tips attached to driver but inserted by screwing it in, as it is threaded and inside of driver head (below screw/nut/bolt receiving area), is identically threaded to receive it

The unique aspect of this invention is the fact that the magnet insert screws into the driver shaft head rather than being pressed in under pressure. The best design for this invention includes self-locking threads as well and the combination of using a threaded installation of the magnet insert and the locking threads is an additional unique attribute to this invention. This unique a threaded install attribute helps prevent the magnet insert from coming out under impact pressure and even if it does it allows it to be reinserted using a screwing mechanism and when reinserted will remain in place unlike existing press-in products. A third unique attribute of this invention is the depression at the top of the magnet insert designed to receive a screwing tools such as a flat head or Philips screw driver, hex, Allen, etc., making it possible to easily reinsert the magnet insert and tighten it firmly in place.
