RDA Velocity clone question...stripping grub screws

[RiderVapor]

What would be a better replacement set up over the grub screws for tobeco Velocity, driving me crazy, help please?

Grubs are best. The only thing is the clone screws are machined so bad that they strip.

I go to Mr. Metric and you can get any type of screw you need, cheap and no minimum orders.
