We can send billionaires to the moon but we dont have a small self taping concrete screw.
Just imagine one day someone will get really smart and design a small screw(M5 and M6) with a large cheese head that will be able to drill and cut a thread in concrete.
Just imagine the time saving ... hopefully one day someone will realise that a simple design masonry/concrete bit as part of a self taping concrete screw would be the next best thing since sliced bread.
The easy hold design was smart but unpractical ... because you cant remove it ... maybe a similar design with a flat head would work?
so take the Hilti HUS-3-P and copy it ... and make it out of strong plastic ... that can be hit into brick or concrete to hold things like PVC trunking or light weight cable tray.
It could be a problem in the UK because they have to use steel supports for their electrical wire ways.
