I had the same problem (and I think several others have also).  Gary told me to use the shorter screws so it would be snug.  They really need 1/4"  screws or deeper holes.  Mine was serial 370.

I Just started assembling my KPA500 serial number 0585 this evening. All was going OK until I got to the point where I mount the Z-bracket to the PA/LPF heat sink. The book sez to use 4-40 5/16" black flat head screws. Using this size screw does NOT pull the Z-bracket tight against the heat sink. I've measured these screws three times and I am certain I'm using 5/16" screws. If I use a 3/16" screw, it works fine. Also, I have verified that I've positioned the PA/LPF properly. So, is the documentation wrong, or is this Z-bracket supposed to be wobbly and not tight against the heat sink?

Thanks, Jim / W6JHB
