However a Phillips screwdriver might do Component of The work, you might have a computer screwdriver established to take care of the various tiny screws in your electronics and computers.
The principle challenge with this arrangement may be the thread profile. As we described within our submit on screw threads, the V-thread profile on threaded fasteners is optimized for offering a substantial axial clamping power plus a “non-overhauling” house, or even the inclination pop over to this web-site for that fastener to self-lock. This needs a higher friction arrangement, which isn't ideal to get a screw travel.
