Hi,
What are the outside dimensions for a #6 screw countersinck? For the #8 screws on the wing spar I found a value between 0.365 and 0.375 inch in various blogs and posts. This worked out fine (used 0.370 inch).
An very old post on this forum mentioned less than 0.3125 inch for a #6 screw countersink hole based on a discussion that followed on the first RVator release. But I cannot find confirmation for that value. For your information I am countersinking the #6 screws for the wing inspection plates on an RV-9.
I just wonder why VANS is not listing those dimensions in the manual because to me this is much more accurate than saying "use a test piece and see if it fits". Measuring is always and everywhere the same. If you drill to deep it will also fit with that test piece technique... but it is obviously not good.
