Torx size - wheel arches

[John0021]

Hi All

The screws and washers on the wheel arches of my 2006 Clio 182 have rusted quite badly so I'd like to replace them with stainless steel. What Size Torx specifically do I need for this particular job. I'd rather not buy a massive set from T5-T55. I've seen some sets begin at T10-T30 but i want to ensure i won't need a T8 or <
Regards

John

If you get a self tapper with a torx head, I don't think it matters the head size. I think it is just self tappers holding them on isn't it?

Would these do?

Standard ones are T20 iirc

Thanks chaps.

you can pretty much take apart a whole Clio with a t20, arches included

Thanks chaps.

Halfords sell them separately, so no need to buy a set if you only need one or two

Hi
Just as a follow-up. If I just want to replace these screws and washers with like-for-like new ones where is the best place to get them from? Are they a standard size? if so, does anyone have the details?
Thanks in advance
