New DIY idea.... your feedback needed!

Contact me through the website www.bladefixing.co.uk. if you want to have a try. It will be fully tested when it comes to market, and I'm confident that it will out perform rivals, as far as grip it goes they claim 180kg yet only say safe weight 50kg shear load, and then say 30kg on pull out load, so that is an example of rival claims, I'm offering an alternative that does more, of course it needs tweaking but the principal works.
 
Also if your concerned about the slot above the fixing, you could put the fixing in horizontal, I have even put two fixings in the same slot in opposite directions, do you not think that would be stronger?

It is not my area of expertise, but I vaguely remember speaking to a colleague about some plasterboard fixing testing for wall sheathing purposes. Plasterboard is a bit crumbly/crushable, as you get some compression around the fixings as it is loaded and unloaded, the actual performance deteriorates over time.

My concern is also still over downward diagonal forces wanting to 'tear' the plasterboard under the slot.

I'm sure your product will work, but I have doubts that you can significantly improve the stated loads vs. other fixings as it is likely the plasterboard that is the limitation and not the fixings themselves.

And personally I would rather drill a hole than cut a slot, and (or but) I am not a professional workman.

I hope this comes across as constructive and not unnecessary picky.
 
I agree that plasterboard has it's limitations, but in a couple of pull out tests I did with it, it pulled the plasterboard off of the studs, yet the fixing was still attached, wonder how many others can do that. Horizontal fixing could be an improved way, but it's already high when fixed vertically. Cheers
