People sometimes mention that the screw they are using wore out, usually at the Phillips socket. Here are a couple of stronger screws. The ones that come with the kit are no stronger than 125 ksi; these are 160 ksi. This is strong enough to maintain shape, and I routinely reuse them. The prices are at Aircraft Spruce.
Pan head:
NAS602-8P
$0.15 each
8-32 .531" long
Flat head:
NAS517-2-2
$0.18 each
8-32 .531" long
You can get other lengths and other diameters of each. On my RV-3B project, a number of applications can use shorter screws. That reduces wear on the screw and the nutplate while saving weight.
