It appears I wasn't very clear on the A12B plate for the SA Operator AOS. The plate has no overhang on the slide fits flush. The Holosun EPS optic overhangs the plate a little over 1/16th inch on both sides.

I think we speak the same lingo.. when you say 2/16ths I assume that is 1/16 on each side(or 2 different locations).
If not, I am sure you would have said 1/8th.
I don't think you understand how screws/bolts work. A #6 screw is 3.55mm. With 48 tpi, there's quite a bit of thread engagement, which is where under proper torque the friction needed to secure it comes from. The instructions for an AOS plate have up to 25 in-lbs of dry torque. If using loctite, you should reduce this 20%, so no more than 20 in-lbs. It's why many recommend 18 in-lbs of torque on screws with loctite for optics plates. Assuming the threads have good contact and form a clamp, either dry or with loctite, they should hold just fine.
Most people don't torque them correctly - you should do it in steps. 6 in-lbs ea, then 12, then 18 (lubricated with loctite). Or 6,6,6,6 if you want to get to 24 (dry).
If you're not measuring torque, you're probably over-torquing, which weakens (stretches) the bolt. Once stretched, you need a new one - they don't "unstretch."
If your plate came loose and you re-secured it with the same screws/bolts, that's why it came loose again. You need new ones, and you need to use proper torque.
