HI Tim many thanks an much appreciatied for havein a look for me on them screws but not the same as i need mores the pity but i have posted a pic of the one i lost an its about 4mm long an across the head 1/an half mm an pointed as got to pull into a 1mm hole the screw below on my finger tip View attachment 392434

Would a pack of mobile phone screws do the same thing. Would be silver but they look similar in size. These can be bought on Ebay.
