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

Abstract

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.

Claims

1. A uniquely designed driver A hardened steel or other material shaft comprising: a Bottom tip designed to fit into pneumatic, impact, hand crank or other tool; and a head (top) designed to receive screw, nut, bolt or specialized tip; and an upper opening in shaft head designed to conform to screw/nut/bolt/tip; and a lower opening, under upper opening, in shaft head designed to receive magnet insert; and threads in lower opening side wall designed to match threads on side wall of magnet insert. This application includes normal threads and self-locking threads that get smaller/tighter near is bottom of lower opening; and can be a variety of lengths

2. A magnet insert sized, shaped and threaded to fit into and be screwed into opening in head of shaft comprising Inner magnetic core (preferably made of “rare earth” magnetic materials); and Magnet insert side wall metal outer shell used to protect the bottom (portions that will touch the inside of the driver head) and sides of magnetic core, preferably made of brass to absorb shock; and Threads in metal outer shell; and this application includes normal threads and self-locking threads that get smaller/tighter near bottom of shell

3. A magnet insert, as in claim 3, whose threaded nature of this invention provides an added feature/benefit comprising because the magnet insert is screwed in it can be removed and replaced at will, whereas frequently existing similar products gather metal debris inside the top opening preventing the screw/nut/bolt/tip head from fully entering the opening and this failing to fully engage with the driver, often stripping the screw/nut/bolt/bit or the driver head, this debris can be extremely difficult to clean out because the magnet holds it inside the opening, whereas under this design it can be easily removed and the magnet replaced.

4. A magnet insert sized, shaped and threaded to fit into and be screwed into lower opening in head of shaft comprising A depression at the top of the magnet insert designed to receive a screwing tool such as a flat head or Philips screw driver, hex, Allen wrench, etc., making it possible to easily reinsert the magnet insert and tighten it firmly in place.
