#1432: WedgeHead

Sick to death of screwdrivers which can’t stay in contact with their screws, today’s invention is a combination which remains firmly together during screwing in or out.

It takes the form of a screw with a tapering notch made in the head. All sizes of this screw can make use of a single screwdriver with a correspondingly tapered blade which fits inside snugly…in such a way that springing out under load is impossible.

This design also allows the user to attach a screw to the driver blade firmly, so that the screw can then be used in places where fingers can’t reach to steady it.

  1. Robertson screw drive already solves those problems. It just never caught on for some reason.

  2. Yeah it looks like greed was one of the reasons.
