Lens Mount Screws.

I've had a little accident using the new HD D-FA 70-210 f4 attached to my K3-II. To cut a long story short both the camera and lens are working as good as ever, however in the process of fixing the lens I managed to lose one of the screws holding the lens mount to the lens.
Does anyone know if there's a website showing the screws, i.e a maintenance manual or know what the screws are (i.e, M?*length) or where I can get one from (the Pentax UK service agent is closed due to Corvid 19)?
I've tried taking the screws from a couple of M series lens but they're much too short, as are the screws in some of more modern lens.

Any help would be appreciated,

Alan

How on earth did you manage that? Obvious question but if you know where it happened is it worth scouring the area again? If you have one of those detectors for tracing pipes and cables in walls maybe it’s worth a try.

We've tried everything to find the screw Rob, no luck. The lens works fine without it, but it's not an ideal solution with the lens only a couple of months old. If it hadn't been Good Friday and everywhere shut I'd have probably posted it back to WEX and ended up with a massive bill, instead I had a go and managed to fix it, minus 1 screw.

Try SRS next week, see if they can help re the lost screw.

How about sending WEX a photo of the mount with the screw missing, point out it must have been faulty and ask for return postage? They should exchange it FOC.

Not if they have read this post!

I don't know about "should", but I guess they might.
Personally speaking, my conscience wouldn't let me do that...

I may be missing something here but can't you take one of the screws that are left back out and have a look at that?

Maybe take a photo of it next to a matchstick or something similar.

This is from someone who refuses to buy from the Chinese because of their dodgy practices?

I think he misread the follow up post (referring to the possible Wex repair and money saved). I'd like to think that people aren't that malicious on here!
