So I've just had and failed my MOT. Turns out the plates I had on (carbon font) were illegal and failed on that. I didn't realise they weren't legal (the eBay listing advertised them as Road legal) so the geezer was kind enough to give me a day to sort it, and said he woudnt recharge if I bring it in tomorrow morning.
Ive bee to Halford and got some legal ones printed, now here's the issue.
I put the old plates on top of the new ones and used them as templates to drill the holes in the new ones. I didn't really think it through and when I looked at the holes in the new ones, they have gone through the letters on the plate.

I don't have any black screw caps to go over them and I'm wondering if it's fail worthy to have silver screw heads in the middle of letters on your reg plate??

I don't wanna fail again!!
Cheers

A lot of cars have silver screw threads in the letters, but if it breaks the black enough to change the letter it will fail. e.g. if an O becomes a C.
Go back to halfords and find their selection of fixings, they should have some black plastic screws, if you can get behind the plate location, or they should have some plastic caps in yellow white and black.

Within reason, it shouldn't be a problem. It's only pretty blatant attempts to deceive that tend to get knocked back. Step back and look at it from several angles, and see whether you think the character affected could be confused with another character.

You could always nip to halfords in the morning and get a black self-tapper - or even a screw cap. Failing that, a bit of black marker pen will help.
