Issue with rear mudguard fitting. Need smaller stay screw..advice needed

[SuperHans123]

I recently purchased a set of full cover mudguards from Halfrauds.
I fitted the front one without issue but when fitting the back one just now, connecting the stays to the 'usual' screw holes meant it rubbed on the tyre.
if I could connect the stays to the lower down, but smaller stay holes, it would fit just fine.
So my question is this, which size Allen bolts do I need that will fit the smaller stay holes?

Pics provided to explain what I am banging on about.
Apologies for picture. Take on a £45 smart phone!

I have never seen mudguard eyes like that. I would go back to Halfords and ask their advice.

Can’t help with your prob but that’s not a bad pic from £45 Smartphone.

Is the smaller hole threaded?

It might be a drain hole which many frames have dotted about.

Looks tiny...small self tapper?

Can't you adjust the stay length at the guard end?

Alternatively, fit secuclips. They're not really needed on the rear guard because a crumpling guard will result in a skid rather than a header, but it'll effectively lengthen the stay by an inch or so.

If you really need to use the other hole and it's threaded and not a drain or optional cable exit, measure its diameter and look up which M number bolt is closest. I think M5s are common but not universal.

Can you not bend the stays a little to clear the tyre?

...except for the picture coming out upside down.

Bike was upside down for cleaning and mudguard fitting purposes.

They are a fixed length type, so no.

Thanks mjr, this was the solution I was looking for.
Bought 2 for £2.45 delivered.
Cheers.

Don't expect the guards to last long. My front one which is 6 months old cracked inside where the stays connect to the plastic. I had to remove it as it constantly rubbed the wheel.
