Outcast Need Help Diagnosing Motor Mount (?) Issue

[slick2500]

Are these the screws where once removed, should be replaced with something like the titanium ones @RedondoBeachRC sales?

I just use socket head cap screws with a washer underneath. I'm having a brain fart and I can't remember what length the screws are but you want something like this. https://monsterbolts.com/products/socket-cap-b12-9-m4?_pos=1&_fid=8130f589c&_ss=c

I actually replace every single screw I can with socket heads they are far less likely to strip than a button head or countersunk screw do to the fact that they use a larger driver and the slot where the driver goes is deeper.
