Anybody Seen This Type of Eye Bolt

04/24/2014 2:41 AM

Does this critter exist? If so, where do I find it???

3/8" or so dia. shaft, threaded one side, 1-2" dia. Eye, 4-6" closed length ???

It would be used to go through a frame or pipe where you needed an EYE on both sides.

Perhaps something like this could be used...

A long coupling nut in the center of thee hole could allow bolts with flush heads to attach to what is above, and it would be very close to what you have in mind.

So, this one would require a threaded bolt and nut on each end to hold it? OK.

Sure, or a barrel nut and matching bolt.... I guess some people call them sleeve nuts and bolt.

Sometimes used in bedroom furniture.

No, you could just use a threaded female sleeve and two standard threaded male eye bolts. I have done this before. My local hardware store carries all this and it is not a large one. I doube if the female threaded sleeve would be available at places like home stores but if you go to a real hardware store they are there. If you don't have one look for them on McMaster-Carr on the internet. Otherwise most ACE, Truvalue, or DoItBest will have them.

Not quite, but, what about a loopnut:-

loopnut

"loop nut"

Plus eye bolt and lock nut.

The part on the left could be made from a regular eye bolt plus a rod coupling.

A turnbuckle might work for you. Otherwise just get two machine-thread eyebolts and connect them with a standoff.

Turnbuckle is too big to get inside of the 2" pipe.

what is a Stand Off? is it like the rod nut?

Dumb question:

On these Rod couplings, the threads go the same way on each end OR do they reverse on each end?

flip your nuts -this may be a dumb answer.

Flip your nuts over.. see? they are reversible with no modifications necessary.

Consider what sort of thread lock device or fluid will work since access inside a 2" tube will be limited.

the part in post #2 is nice because you can use it on one side of a regular threaded eye bolt and have access the parts externally but a cap nut takes up a lot of space on a tiny part like that.

You might be able to source a rod nut that would be long enough to bridge the interior diameter of the 2" pipe. If you want to get spiffy you can grind a small radius into the ends.

That's where I would start looking.

good luck

Two Eye Bolts and a Coupling nut seems to be the best fit.

Thanks to everybody for the comments. This should work and should not be hard to locate either in town or on-line ( McMasters has everything........)

Re: Anybody Seen This Type of Eye Bolt

04/24/2014 9:26 AM

In these Tucker Trawls, the Eye-bolt goes all the way through and the net is lashed onto the frame. On the rig I am working on now I need to have an eye-bolt on the netting side also, NO lashing......as the net will be several inches off the frame. * net will be quite different in shape and design. In the past I have just used two Eye-bolts and off set them...it works but takes time to do and looks ugly. This coupling thing or Loop Nut makes more sense. See, ol' dogs can learn new tricks with a little help from CR4.

From your picture, I can't tell all the functions and stresses that this eyebolt have to endure, but check out "eye straps" to see if they might work, while giving a lower profile. Two of them could be through-bolted with flathead screws and a flathead barrel nuts (and some locktite). Very sleek. Some eye straps are designed to prevent thin lines from being pinched and snagging where the loop curves in to the base (the PVC pipe in your case). I don't know if these would work for you, but they're a slightly different approach that are worth a look.

Yes, just buy a female threaded standoff from McMaster and two eyebolts from McMaster and you should be good to go.

The worst case scenario is that you may need to cut some of the threaded portion of the eyebolt off to make them fit.

It kind of looks like a turnbuckle. See a supplier of turnbuckles and they may be able to fit your needs.

.......this would work if I had a larger dia. frame. However I only have 2" dia. to deal with and a turnbuckle sticks way out side....as is shown in the pictures, I need that Eye to be right against the frame or it will bend and/or crack the elbow coupling when the net gets jerked on.

thank you for the suggestion though. A very short x 3/8" turnbuckle would work.....as will that Rod coupling.

Perhaps something like this large enough to encompass one end of the elbow coupling.

The remaining side would need to be drilled and tapped and counter sunk from the inside allowing a second eye bolt. to mounted on other side.....

If youi used a turnbuckle to couple the two eyebolts, one of the eyebolts would have to have a left-hand thread. This application needs something like an NPS (iron pipe) coupling, only smaller.

Does the threaded bolt stop here and lock itself....or do i need a nut on top ( inside the Eye itself) to stop the threaded bolt from turning?

Put a standard hex nut onto the stud or threaded rod first. Then thread the eye nut on so it is just flush and the stud does not protrude into the eye opening. The hex nut can then be tightened against the outside of the eye nut.

As I said in post #4 you will need a lock nut (either inside or outside the loopnut).

If you're OK with putting the locknut on the outside then the above simple loopnut will be OK.

If you're OK with the locknut inside the loop or eye in the above: again you're OK.

However if you click on the links in post #4 you will see lots of other loops or eyes which will surely accommodate a locknut on the inside of the eye without compromising the attachment.

They are called turn-buckles. Some have open and closed nuts.

McMaster would carry them. as well as fastener suppliers Like Fastenal.

Re: Anybody Seen This Type of Eye Bolt

Considering you are dropping it in the drink I would suggest permanently mating one side of the assembly and using longest possible threads on the other side. With the coupling nut option you could have one eye bolt cut to engage 4 or 5 threads. Clean, install and TIG weld the eye bolt to the coupling nut. With this you will only have one set of threads and the area of engagement will be considerably longer. Add a little LocTite and it will remain removable but should be very reliable. Two sets of threads is asking for something to back out at the worst possible time.

Generous application of LocTite should work as anti-seize, anti-galling and threadlocker.

Similar comments if using turnbuckles.

Also consider positioning the coupling nut (before welding) such that the free eye bolt will come into contact with it and allow you to torque the eye bolt at the proper separation distance. This might help with vibration and it also might help prevent someone from screwing it down into the pipe or leaving it way too far out.

http://www.miamistainless.com.au/wire-balustrade/eye-bolts

This is a supplier for stainless steel balustrade fittings. You can match an eye bolt with female threaded eye or you can use a 6mm turnbuckle ( the barrel diameter is only 10mm ) you can get clevis pin ends, stainless wire rope and cleats.

On the same miamistainless page, consider a different type of fitting altogether-- the "fixing plate." A similar piece of hardware goes by the name of "eye strap." Both of these offset the attachment hardware from the loop, so that the former won't interfere with the function of the latter.

Fine The bolt may not be uncommon but if used to lifting lugs please note the load bearing capacity. The common link between the EYES is a rod with tubular but / socket joint which may result in reduction of loaD BEARING APACITY. ELSE IT MAY BE CHECKED FOR SUITABILITY DEPENDING ON YOUR USAGE..

A google search for "internally threaded pipe" may yield your cheapest solution.

Use 2 Eye Nuts and a suitable length of studding.

What you have illustrated is called 2ea "Lifting Eye Bolts" and a rod coupling or coupling nut. The difference between a lifting eye bolt and an eye bolt is that the lifting eye bolt has a continuous eye, either by welding or casting, while the eye bolt has a simple bent, on a mandrel or bender, eye on the end. For comparable sizes the eye bolt has much less strength than the lifting eye bolt since the eye on the eye bolt is able to "bend open" due to the weight exceeding its lower normal lifting rating. If the illustration, as you have depicted it, were to be assembled you should put a hex nut on the male threaded portion of each and draw it tight up against the rod coupling. These will act as locking nuts and keep the assembly from coming apart. The lifting eye bolts are available in the range you are looking for.

Lifting eye bolts get their name from their normal use, an eye with a threaded stem most often used to attach a lifting rope/chain/shackle/etc. to a motor, pump, gear box, etc. for lifting.

The rod coupling/coupling nut gets its names from its normal use of the coupling of 2 or more threaded rods end to end to make them utilizable as one longer threaded rod.

Both of these items are available in stainless steel. 316 ss will be better for salt water since it is more compatible with salt water. 304 and 308 normally develop"worm hole" type pitting.

Good Luck, Old Salt

That's just a fancy looking turnbuckle. I sold hundreds of them at my Dad's hardware store to farmers.

The standard turnbuckle has a longer bigger diameter "nut", that allows easier grasping for turning, and if you care to use it incorrectly, it is open so you can insert a screwdriver for added torque. Is the size of that an issue?

Turnbuckle is too large to get inside of 2" pipe. It will stick out and bend. I need, short and thick. Thank you for the information though.

Missed the similar comment in an earlier post.

Are you going to be able to use the modified turnbuckle you are seeking properly? The center is what turns so you don't twist what is hooked to the eyes. If not you will have to preset the position of the eyes then hook up your attachments, but this defeats the purpose of the turnbuckle - to tension the attachments. You could certainly make what you want from a turnbuckle - discard the supplied center nut - the center is just a machined double nut with a right hand and a left hand thread - take a piece of round stock, drill through with a tap drill, and machine in the threads, or even better, a hexagonal rod would allow you to turn it to tension the attachments. An easy task for a a machine shop. Where I work we could make that in an hour or so.

Yes, they are called Turnbuckles.

Turnbuckles are not the item this person needs. The best item is two standard right hand thread eyebolts, a threaded sleeve about 1 1/2 inch long that has a through thread, all right handed. We do this all the time around manufacturing plants and the items are available in most hardware stores.
