7075 Aluminum Hex links

patooyee · Sep 30, 2012

What size are the people using with the 1.25" rod ends? 1.75? 2?

2in or larger

Good luck finding the 7075 in hex. My suppliers in Nashville can't find it.

Are there any advantages of running hex over round other than appearance?

patooyee · Sep 30, 2012

From a mathematical stand point, there is a very small strength increase in the 6 directions of the points of a hex as compared to the same size round. I wouldn't say it is enough to choose hex over round though. I just want hex to be like all the cool rock bouncer guys on here. :tc

... Unless its more expensive, then my cheap ass is getting round.

The 6061 hex is easy to get and it seems to be holding up under the rigs I've seen running it.

IMO I would never run 6061 links. At just me....i've seen a bunch of them bend, break or split at the threads. Stay away from 6061. For the small cost savings you will be behind after you have to build a second set.

I have two very used 2-1/2" round 6061 links 45" long drilled and tapped for 1-1/4 heims ? $150
Also two 2" 25" long 6061 drilled and taped for 1-1/4 $75 (only one is bent)

I bought 24 feet of 6061 t6 back when all the cool kids said it was the best. Then some one on pirate said 7075 was better. But I have not seen a failure that would not have happened anyway.

Just to add to the discussion 7075 lists as ROUGHLY double the strength of 6061 in every category:

Tensile Yield Shear
6061 45,000 40,000 30,000

7075 83,000 73,000 48,000

It takes 3 times as long to cut in my saw as 6061 does.

I can't tell a Differance in my saw. But machining 7075
I can tell it is a lot stronger/ harder to machine.

I did not say it was not stronger, I just said that I have not seen real issues out of the lesser. Some one I know ran .120 upper links on a buggy for a long time and had little to no issue.
