My 12 year old with a passion for making jewellery has invested her birthday money in a little drill for drilling into plastic/resin so that she can make add eyes (for necklaces/earrings etc). All is good, except that when she goes to screw the eyes into the plastic they keep snapping when they are almost in which invariably ruins the thing she is screwing them into because you then can't extract the broken screw. Can anyone advise on good quality eye screw (about 4mm) which won't snap? I know that eye screws are cheap and readily available on the internet, but are there any which aren't weak and brittle?
