10mm Yellow Crimp Ring Terminals

That Screwfix ratchet crimp tool is described as 'Ratchet Crimping Tool for 1.5sqm to 10sqm' which is clearly nonsense.
The terminals the OP pictured are yellow, so for 3 to 6 mm² cable, and he needs the size that will fit a 10mm diameter terminal. The RS one linked to in an earlier post is out of stock. The ones I bought recently from Vehicle Wiring Products, product code YR10, are £1.18 for 10 or £4.43 for 50, and they arrived the day after ordering.
I always use the pre-insulated ones as pictured, and usually cover with a bit of adhesive heat shrink after crimping. Never had a failure.
 
I obviously didn't make it clear, I thought the fact that my picture showed two similar but not identical parts made it so. My mistake, sorry for wasting your time.

I can find any number of terminals like the one on the left. It is the one on the right that I need, with much thicker sides.

The last I bought from them were of the thicker / wider ring type (as per your original post) ;)
If IEM don't have what you are looking for you will have a hell of a job finding it elsewhere - they seem to stock just about everything one could reasonably be looking for in the way of terminals and much more.

Why? it has three indent tabs rather than the three fixed sizes of the pre insulated type crimpers , it's just not like the nasty three size pre insulated crimpers, it will do proper solid lug crimps in the sizes it quotes quite adequately for the DIY user, I did actually use a customer's one the other day as I couldn't be arsed to go back to my workshop for my own pro model. The "harfrauds type" red, blue, yellow terminals are the bain of my life, always pulling out or chopping strands because they have a hard edge and can't be properly inspected, that's ones I come across and have to remove on a regular basis. I would not touch them, indeed I am not permitted to use them under the standards I have to work to.
"11.14 Each conductor-to-connector and conductor-to-terminal connection shall be capable of withstanding a tensile force equal to at least the value shown in Table 1 for the smallest conductor in the connection for 1 min, without separating"
Those things more often don't than do, they are capable of doing so but the compressibility of the insulation material makes it hit and miss, much better (and actually cheaper so that should appeal to PBO types) to use un insulated "ass cheek" terminals with boots or heat shrink as appropriate, also looks neater and a more "proper" job and far more controllable.

Totally agree, and anybody who doesn't do the "pull test" on the wire after it has been crimped is asking for trouble. Then there's the cheap aluminium crimps that you need to watch out for, if you have any of those, they need to go in the marina skip.
 

Because they have no idea about cable sizes and metric units of area. The crimpers themselves are probably fine, and look very similar to the ones I use, but I don't think they are man enough for a cable with a csa of '1.5sqm'.

ps Nigel - I have just looked at the yellow 10 mm ring terminals I got from Vehicle Wiring and they look like the larger version rather than the skinny one in your photo.
