Avtex TV Stand Screws

I don't know if the size is different, but I'm sure, somewhere!, I have the screws from the stand of our series 7.  Don't need them because the TV is now mounted on a wall bracket.

Realistically, they will only be M4 or M5 size, and being but a few pence buy sets of both. 

The issue will be  the required shank length, and sometimes too long can do real damage where the screw goes through and contacts something it should not. I would test  gently with a cocktail stick before going to B&Q etc. They only need to be long enough to do the job, so that little bit of homework should sort out the length to buy.
