Quick question about the flat head screws used in rc10s: do the 4-40's also have 100 degree heads, or just the 8-32's? I cant really tell by looking at them, and some of the 4-40's i have look like maybe they are 100 degrees and others don't. I may order stainless screws for my b1m and want to get the correct heads. Thanks.

4-40 are 82*
8-32 are 100*

For info only, metric are all 90*

Awesome, thanks Jeff
