nut for 6" threaded rod

[par060]

Can anyone give me any dimensional information or a place to look for that information for a nut that would be used on a 6" diameter threaded rod?....thanks in advance

Then you also need a wrench and someone (something) to turn it??

No I will leave that up to the Contractor. Those cheap flea market socket sets should have a incher in that little box.

St. Louis Bolt and Screw will make a custom one for you if you can't find one anywhere else.

what kind of structure requires 6" threaded rod.

 

[par060]

Its actually going to be placed horz. thru the top chord of a truss and hold some verticle rods on both ends causing alot of bending....tthere is an exiting 6" diamter hole that used to hold a pin that this new pin/bolt is going to run thru...there are some interfrences that make this the most efficient connection

I am sure Bob is right. I live there and they can do just about anything - Actually any good machine or screw shop could make it.

But in college (many years ago) I worked in the fastener department of a large company. One day we got such a nut in for a customer and it weighed about 250 lbs if I remember. It was used on a bridge.

Google should be helpful.

If this is a pin with tension hangers hung from the ends, does it need to be a threaded rod? Big pins typically are smooth rod, with the ends drilled and tapped for a closure plate to screw on. The hangers might complicate that, so you might consider using welded studs of a smaller diameter which can receive a closure plate. Trying to use a 'nut' sounds like a strange and cumbersome solution.

"Then you also need a wrench and someone (something) to turn it??"

Long ago, I worked in a shop and one of the tools in the toolbox was a 60" pipe wrench. The unique thing about it was that it was BENT.

The story behind that was that the hydraulic cylinders on trackhoes had ends that thread off, which was normally a job involving a hammer and chisel, much time, and application of select words. (The ends had little notches around, not flat sides like a nut.) Someone got the bright idea of buying this giant pipe wrench to speed up the process, and they then used another trackhoe to turn it. The wrench had a gentle bend to the side.

Anyway, this website:

http://www.loharforging.com/special-fasteners.html#heavy-duty-large-size-bolts-and-nuts

shows "EN-Series Bolts and Nuts" in sizes up to 6"/150mm.

A number of the DIN thread standards address threads over 150mm, so presumably nuts are addressed somewhere also.

You might also consider SuperBolt nuts.

Actually it really doesn't need to be threaded rod .... I needed aa material that had a Fy of 70 ksi and the existing hole is 6" diameter ...I found A193 fit the bill. so I slip this "rod" thru the hole and I have to attach 2 rods to both ends.....so really I suppose I could have a 6" pin...then thread down the ends to 4"....put a vertical plate on with 2 lugs to hold the vertical rods that are in in tension ...and then a 4" nut to hold it all on to the pin.

Now you are thinking. Keep it up. There are several ways of doing this. If an architect is involved, some solutions will make him happy, some not.
