If you drill the correct sized hole for the screw you're using it won't back out. Use a bedding compound / marine caulk, not silicone, to seal the screws in the hole. This will prevent water intrusion and crevice corosion to the screw. Here's a suggestion for screw size to drill bit size:
#4 use 3/32"
#6 use 1/8"
#8 use 9/64"
#10 use 11/64" (or 5/32" in a pinch)
#12 use 3/16"
