Where can I get 10mm long M6 metal bolts to fix my numberplate, which come with coloured bolt caps?

I wanted to replace the rear numberplate fittings on my 2018 Karoq (they looked ugly and one side was loose). Ordered a set of numberplate screws without checking (my bad), took the plate off and realised it was bolts. Returned and ordered a set of M6 numberplate bolts. When they came I saw they're 25mm long - and wherever I look online it's actually only 25mm bolts. But my numberplate holes are short and can only take a bolt of maybe 10mm length max! I can see that whoever attached the numberplate last McGyvered it - one side is a cut-off plastic bolt, the other side is a metal bolt but looks like it was filed off and it doesn't fit properly.

I know I can get 10mm M6 bolts from a DIY shop, but they don't come with white / yellow / black coloured bolt caps, because they're not sold specifically for numberplate mounting.

So I am just really confused - is Skoda using a weird numberplate fitting, and if so, don't they at least sell replacements? Do I have to go to a Skoda dealership and ask for a set??

You can get coloured plastic bolts that are easily cut to size if necessary, eg:

eBay UK

Nylon Plastic M6 Screw Fixings, Nut & Bolt, Car Number Pl...

Nylon M6 Screw Fixings. Nylon plastic M6 screw fixings - new from manufacturer. Kit includes nuts and screws - the nut will be black for each colour option of screw available. Includes screw and nut.

Ok thanks, I didn't think that cutting them down is a done thing. Seems so half-arsed? Also I wanted proper galvanised metal screws with nice caps rather than these plastic things. Where do Skoda get the actual screws that their numberplates are attached with, on new cars? I'm probably going to have to either get 10mm bolts from Toolstation and not have colour caps - or get the bolts and then use caps from the 25mm bolt kit I bought (so I'm paying twice). It's such a small thing but seems absolutely insane - why does my Skoda have different size fittings from most cars out there?

Can't help further I'm afraid. Last time I changed a numberplate was 1997 & that was double sided tape...

I'll check what's on mine in the morning if I remember.

Edit

Had to grab something out of the car so checked & they're plastic bolts.

Thanks for checking! That's cheap, lol. The plastic one that's in my number plate (if that's an original one) is all chewed up and isn't threading properly. I think I'll try getting 10mm metal bolts and using them with the caps from the 25mm bolt set.

I'd think that it will be up to individual car sales places what sort of number plate fixings they use - so not a specific Skoda issue.

I bought an ex Channel Islands hire car Ford Fiesta many years ago, it was being sold by a Mazda dealer locally, how they fitted the UK mainland number plates was just to hold the new plates roughly level and drill a couple of holes through the plates and plastic bumper cover - rough as badgers bottoms, Ford always provided mounting points on their cars. I think that that annoyed me enough to buy a set of new plates and fix them properly using stainless steel screws and correct colour caps.

That sounds incredibly lazy by the dealer, especially when proper mounting points were already there.

@oryxspirited yes, disappointing really, still what I was buying was a 3 or 6 month old Ford Fiesta 1.1 Ghia 5 door, with maybe 1,500 miles on the clock, for very little money, so my wife was getting her next used car which was almost new for a change!

There used to be quite a trade in these ex-Channel Island hire cars, mainly Fiestas and Nova/Corsa in UK back in 1990s, just another way for Ford and Vauxhall to boost sales figures - none of them came with manufacturer warranty though, which typically made no difference to the typical buyer who could sort out most issues themselves.

Only issue was trying to get rid of the very fine sand in the cabin!

Edit:- I had to get the salesman to retrieve the "lock number" tags from his wastepaper bin along with maybe the "sports key" which was a small skeleton key typically only ever used when you parked at the beach and went swimming etc.
