I do agree that there are shit loads of ways to skin this cat. Just saying that all but carriage bolts are NOT all wastes of time and money. But, I am confused, how do you install a carriage bolt without access to both sides? Don't you have to push the bolt in from one side and install the nut on the other. Yep, I'm thinking so.
not sure where you read offense.
But the low boy semi trailer sitting at the side of my house has carriage bolts holding its decking on and that pretty little horse trailer sitting next to it does too. My utility trailer has the screws. But it hasn't seen the same amount of time on the roads as the horse trailer or the low boy (that low boy is probably 30 years old)
But you're right, guess you have to drop the bolt in. And sure not all screws are wastes of time and money, but as the OP has found, it did not work out well for him. I'll modify my statement to be "carriage bolts with locking nuts and washers are the only way for ME to go"
