I had this problem, as well as stripping out the Phillips head. Drilling is important. A little wax couldn't hurt. I added to that buying a box of high quality stainless steel screws. I don't think I ended up using any of the screws that came with the kit. I had some old jazz bass pickup screws laying around that I wish I had replaced with stainless. All the others I did replace. I have not regretted it

Besides, what is the point of having a screw you have trouble putting​ it in or the shaft's not hard?
