I am furnishing my third Essbox. This one will contain plugs and screws. I bought quite a few plugs, but now I need to buy screws for the plugs as well. What would you recommend for screws for each plug below?
Plug 1: It just says 8 on it. It is 4 cm long.
Plug 2: It says 6/50 on it. It is 5 cm long.
Plug 3: Brown, it says 8/40 on it. It is 4 cm long.
Plug 4: Blue, it says 10/45 on it. It is 4.5 cm long.
Plug 5: It says 10/60 on it. It is 6 cm long.
I assume that the first number indicates the drill size to use and the second number is the length of the plug itself. But which screws should I use for each plug, do you think?
It depends a bit on the type of plug but follow the recommendation (always choose the larger dimension) here for a standard universal plastic plug and it will be fine: http://www.vsbyggskruv.se/pdf/sid52.pdf Generally about 20-25% smaller screw than the drill diameter.
But don't make it so darn complicated, it's not like you're assembling a space shuttle.
Use a screw that fits in the hole and tighten it properly. In stone/concrete, it doesn't need to be longer than the plug, but if you have a universal plug in sheet material, it will be easier if the screw is maybe 1cm longer than the plug.
How much longer should the screw be than the plug?
It depends on the thickness of the material you are fixing with the screw. But in the final assembly, the tip of the screw should reach through the end of the plug, the "cylindrical part" of the screw should reach the end of the plug, that's when the proper expansion of the plug occurs.

Benjamin: Yes, a fitting screw was what I was looking for.
"For optimal strength, it is recommended to drill the hole depth equal to the length of the plug plus 2 times the plug's diameter. In soft materials such as leca, siporex, or similar, use a hole 2 mm smaller, and in very hard materials, a hole 1 mm larger." http://www.imexab.se/swe/alligator.html
"SCREW LENGTH FOR PLUG
When choosing a screw for a plug, keep in mind that the screw should have a length corresponding to the length of the plug + the fixture and an additional approximately 5 mm. This is to achieve full expansion of the plug and thereby the highest strength of the fastening." http://www.vsbyggskruv.se/pdf/VSB_Infastningsguiden.pdf
If you screw into a wall consisting of OSB and gypsum, do you gain anything by using a plug or is it just as good to screw directly into the wall? For example, if you are going to mount a wall bracket for a TV.
But don't make it so darn complicated, it's not a space shuttle you're putting together.

This is totally wrong. It is important that the screw is longer than the plug even in stone/concrete. The most common reason that the screw and plug fail or do not reach the load they should handle is not the wrong type of plug or wrong screw diameter but a screw that is too short.

I don't use the specific plug types you have, but doesn't the box indicate which screw size you should have? Also, avoid screws with a cut in the thread at the front (like essve cutters) as they can damage the plug. Usually, plug installation should also be done with full-threaded screws (depends on what you're attaching, though).
Blue and brown plugs are classics, although surpassed by modern plugs nowadays. However, they work well in materials like stone and concrete, for example. For blue, you should use about 8mm screws, brown about 6mm, and the length depends on the thickness of the material you're attaching.
Use a caliper to measure the outside of the anchor, take a drill bit that is slightly smaller and drill.
Use the same caliper to measure the inside, take a screw that is slightly larger than the measurement and screw it in.
If you are drilling into drywall, the hole tends to become too large, start with a drill bit that is about 0.5mm smaller than the measurement you have determined.
Wasn't there any information on the packages you bought with anchors about which drill bit diameter you should use?
let's get back down to earth.
The most common reason for needing to hang something on the wall. Often, you've bought something that often includes brackets.
From this, you dig out a suitable plug from the collection, which usually consists of 4-5 different types/diameters.
What needs to be screwed into the wall has a bracket/screw that is sized for what needs to be hung up, i.e., the screw size is usually given, or the instructions tell you what is needed.
If the plug happens to be 5mm too short or long, it will not cause the TV to crash to the floor.
Therefore, I insist on using a suitable screw and using the plug that fits best in the plug box.
This is totally wrong. It is important that the screw is longer than the plug even in stone/concrete. The most common reason for the screw and plug failing or not reaching the load they should handle is not the wrong type of plug or the wrong diameter of the screw but a screw that is too short.
It was a bit awkwardly phrased when I wrote it backwards and assumed that you choose the screw based on the plug and not the other way around.
I would start by replacing plugs 2 to 5 and replace these plastic plugs with nylon plugs. Then buy Essve's plugs, and the box will tell you which screws to use.
