[TowerTalk] 5/8 "Washers" on Bottom of Bolts

[Wilson Lamb]

I'm no concrete guy, but those bolts seem short to me.
The small heads will create high compression loads, depending on how much tension is taken out by the threads above the heads, if there are threads.
The heads are so near the top of the block that a lot of the concrete will have to go into tension, not great.
Just think; those little bolt heads are the only thing relied on to mobilize the strength of that giant blob of concrete.
I'd like to see the suggestions  for alternate bolt configurations, if you can post them.
I can't give numbers, obviously, but would like to see longer bolts, with sizeable washers.
Fine "washers" could be made by buying some scrap plate, cutting some pieces of  4-5 sq inches and burning holes in them.
Who knows, you might find a pile of cutoffs in the junkyard.  I think 1/2" thick would be OK, but you may find 1/4" plate more available and it could be doubled up.
I know doing this at machine shop rates would be unreasonable and that you may prefer buying, but I enjoy such making do.
If you haven't already bought the bolts, why not get J bolts, which solve the problem very elegantly?
You could weld the bolts, well, maybe a trained welder could, weld the bolts to some rebar as long as you like, with a L bottom.
