M4 spring toggles for CCTV fixing - available anywhere?

[c128]

I have a a CCTV IP dome camera that I want to fit onto UPVC soffit.
The camera itself isn't particularly heavy, and it's quite thick soffit - the load isn't really an issue.

The camera has 3 mounting holes that fit an M4 bolt pretty much perfectly, with a small rubber gasket that makes a nice seal. M5 would be too big and M3 a bit small.

Ideally I'd like to fit it with spring toggles - I can actually get to the back of the soffit where it's mounted, so the hole itself would only need to be 4mm-ish and I'd manually but on the spring toggles behind, then tighten at the front. Don't really want to fit any sort of noggin, as toggles would be neater.

Thing is...I can't find any M4 spring toggles anywhere. Well, that's not quite true - there are some in Australia:

M4 seems to be a weird size, at least for spring toggles - anyone know where you can get any in the UK?

It it's not heavy and the soffit is fairly thick why not use self tapping screws?

Well, could do, I guess, but I kind of like the neatness of a bolt and toggle. Also seems a bit more secure, and would spread what load there is a bit more.

Could just fix it with M4 bolts, nuts and a large washer, I suppose, although that might be a bit fiddly - I have some access behind, but not loads. Bit surprised that toggles aren't available in M4 more readily...

As said, just use screws or as you wrote nuts and washers.

Spring toggles are rubbish and are pointless if you can access the inside.
Plus they aren't neat which is one of your reasons for using them.

Hollow wall anchors would be better but you need the tool to fit them.

toolstation do these in M4

and they will spread the load onto the soffit, also if you need to remove/replace the camera the fixings will still be in place

Ta all.

Actually ended up using some M3 spring toggles in the end...as it turned out I already had some to try it with - only needed 3mm holes for the actual bolts, toggles screwed on mostly from behind and then tightened from the front - more secure than I thought it would be. If the camera ends up going at some point in the future then there won't be much evidence it was there.
