Had a very slow tyre leak over the past year losing about 3-5psi each month. Did not worry me too much and just inflated regularly as required. I knew I would have to do something about it one day when I had more time. That time came last week. So, I removed the wheel from the car and inspected the tyre. Sure enough there was a 50mm nail embedded in the tyre. Pulled it out with multi-grips and partially replaced nail into puncture to avoid further air loss.
I came across ads relating to the screw type puncture repair and looked further into this process, and decided to try this out on my current puncture. I inserted one of the screws into the puncture hole with a phillips-head screwdriver, as per instructions, inflated the tyre to recommended pressure and tested the area with water for possible air bubbles. All seemed good. I have been driving on this tyre now for over a week and there has been no pressure loss and the screw seal is looking good.
There is actually no need to remove the wheel to perform the process. Jack the wheel up and inspect the wheel whilst turning, remove cause of puncture and replace with sealing screw. The screws come in two sizes and are very cheap.
I have plugged quite a few tyres in the outback, & it's hard work at my age pushing the needle & caulking thread into the tyre. Pulling back out is easier.
Also one time the ARB handle broke around the allen grub screw, luckily we had a pair of clamping vise grips.
Another car we had to put 5 plugs into the hole. A longer story, but that was not the worst tyre!
Anything for a range of plug options is a good idea.

I suggest that plugs and screws are great for short term repairs but are not approved techniques for long term repairs and nothing is approved for sidewall damage.
Internal patches are much more effective.
We carry both.
Just don't tell your insurance company because if that tyre fails and there is damage to the vehicle (or worse) and they see this repair, you might miss out on any claim.
