Ensure stud, washers and nuts are corrosion resistant (stainless or galv).  Clean the drilled holes thoroughly.

I'd cast in J bolts for that as a "holding down unit". Hooked round mesh going down into the concrete.

 

Don't get me wrong I love chemical anchors.

Your gate kit should have them included or at least the spec. Mine required 12mm SS rods cast into the concrete. Think they had to be 250mm long, 50mm proud, 200mm set in. A rather large sliding gate tho.
