We always put at least 1 5' glass rod at the primary fitting and we wil run multiple glass rods through the primary as compared to using a strut guy to go over the primary like they do in Florida, I will post a picture later. We never bond our guys to the neutral. We only install a hubbard clamp on our neutrals no glass. I have seen them a little in my travels in the states, some in Florida, but they use glass spools more. I prefer the hubbard to the spool it helps with bonding the pole and I see no advantage to isolating the neutral from the pole and likely you have messenger below that is clamped directly to your pole and periodally boneded to your sytem neutral anyway. When it comes to applying grounds we never use the bolt, but always apply our ground to the neutral as you are correct the bolt is not designed for fault current.
