[Elecraft] KX3 Kit Builder Alert #1: Battery holder attachment screws

I experienced a "hot" cell when I loaded Lithium cells into my new KX3 kit.  I thought that it might have been caused by the cell shorting at the spring.  I removed the cells and used my station supply until I could get some rechargeable cells.  
I saw the subject "Alert" and checked my hold down screws and found that they did "stand proud" and protrude above the base.  I thought that the screws were too long, but when I removed them, I noticed that the holes in the battery holder were not countersunk for the flat head screws, and this was what was keeping the screw heads from being flush with the holder.  The heads is quite sharp, and may have been cutting into the cells.  I also noticed that I had difficulty getting the two halves of the radio to come together completely .  I thought that the cells were over size, but now I think that they weren't lying against the base of the holder.  I am thinking that I should countersink the holes, but wanted to check what others had experienced.

Thanks,
