just had a look at WD Music, the screws on my pick guard, actually I suppose it's more of a scratch plate, anyway, the fender screws have a curved head look different to mine which are flat :/
update: just took a screw out and measured it, diameter of the pick guard/scratch plate ones looks like it has a 2mm thread rather than a 2.5mm of the fender, but I am using a tape measure
