I am building a shed in my backyard and want to build it to code, and I
need to have some tie downs for it at each corner.

I could use some mobile home straps that get sunk into the ground, but I
sort of prefer to use something like Simpson Strong tie down threaded
bolts dirrectly into the concrete pad and then up through some concrete
block and them bolt down the sill plates to the rods, but no one in
Raleigh NC seems to know about them.

DOes anyone know if you can use regular threaded rods available in
hardware stores for the same purpose?

I was also thinking that I could use some kind of steel or iron pipe -
3/4 or 1" size - down through the block, but that is kinda complicated
to do.

ANy suggestions on where I can buy this stuff around Raleigh, NC? Reply
to the newsgroup - thanks!
