Blind bolts

[bluedog225]

I’m thinking of using 1/2” blind bolts to fasten H-beams to a piece of square metal tubing. Preferably hot dipped galvanized. I will run the answer by the engineer, but I wanted to do some legwork first

What brands should I be looking at? Thanks.

Hilti, Simpson, Portland Bolt. No luck.

Something like this. I’ve managed to find some, but they all seem to be British for some reason.

This is the top contender so far. Even at 20 bucks a pop, it might be a cleaner install and cheaper than welding.

How is that cheaper or easier than welding?

I think you can get Hollo-bolts from Fastenal? For some reason I see them at the places that sell a lot of unistrut.

If you can't weld, or don't have a welder.

Don’t know. But wanted to price it out. The stuff is hot dipped. I’m told that that’s a pain in the *** and takes longer.

With the right tool, 30 seconds a hole.

I didn‘t realize those were a structural option.

I wonder why the “na” on some of the stainless.
