Regarding the socket cap screws for your rails i think you will find that these are 5mm, the clearance in the hole is to allow you to adjust the rail to get it straight. i was going to reply yesterday to your post but without any design drawing to eyeball there was no input i could give.
Don't give up.

Thanks Mike

Appreciate that - I thought on top of everything else - something as basic as that - i was just getting frustrated!

Do they have to be socket cap?

There are that many different profiles of 'machine screws' i thought as long as they are stainless steel.

I have bought quite a few different types - but guess what, not socket cap.

Can anyone point me in the direction of a really good website for these kind of parts -

Buying off Amazon Prime for 20 screws per time starts to work out expensive, especially when i need about 128 just to fix the rails on

Thanks again

I would prefer the steel screws, you can get plastic plugs to seal the countersink in the rail but check on the engineering drawing for your profile rails to see how deep the countersink is.

Ha - now there's the joke!!

There is no engineering drawing for the profile of the linear rails, I had to use a digital calliper.

I did check on the sellers website - i could have checked and used others, but thought that i could not guarantee that the profile is exactly the same

There is a technical drawing for the aluminium extrusion though.

Thanks for the links
