Chain quaility

Does a G70 chain from Harbor Freight meet the strength and breaking specifications required of these for use in trucking tie down chains? Does anyone test this stuff? I had a guy tell me he stretched such a chain.
 
Hello centerplate,

grade 70 chain is the one use for deck lashing, logging railways construction, among other uses. If it is marked a 70 grade it should be 1/4" 7 MM. It is rated at 1410 KGs, or 3100 pounds. If it is marked that way, I would think it is that capacity?

I've stretched a couple of them!! My fault though.

I suspect that unless you buy a high dollar name brand chain, most of it comes from the same factory.

That said, if it is gold and has the G7 or 70 marking DOT should be happy.
 
The grade means it has to meet certain specifications. If it does not meet those specifications they cannot claim that it meets that grade.

Harbor Freight has 5/16" and 1/2" chain in G70. They do not have 3/8" chain in G70, which is very odd because that is the most common type of chain and they'd sell a lot of it if they had it.
 
Barnyard I see that HF does not sell 3/8". Kind of odd to not have that.
I did some more research and Cargo Control looks to be a good supplier of such products. They did have two listings on some chain and the American made is higher priced leading on to believe the cheaper stuff is Chinese.
 
Harbor Freight does't have or handle 3/8" grade 70 chain because they haven't found anybody that they can buy from cheap.

FWIW, I've seen plenty of "good old American" G70 chain that was stretched or crushed. Never underestimate the determined efforts of your average fool.
