Am I looking for a "threaded insert"?
Am I looking for a "threaded insert"?
(OP)
Hello,
I am looking for something quite like a threaded insert, but threaded on both sides.
In other words, I could take this part and attach it the same way I would a nut and a bolt, but the end result would be a hole for a smaller bolt to fit inside.
Am I making myself clear at all? Does this sound like something you would still call a threaded insert? If not, what is it? Does anyone know a good supplier?
Thanks so much.
Cheers,
DHD

Threaded pipe bushings are threaded on both sides...
I'm guessing you want something with machine (straight) threads on both sides, in a solid insert...
Keenserts have an o.d. thread, with knock-down locking "keys", similar products without keys but with threadlocking compound on them exist too. Both of which can be found by typing "threaded insert" into the search blank on www.mcmaster.com.

Want machine threading on both the inner and outer surfaces.
I'd saying something like 10-32 inner and whatever size the o.d. has to be to make that i.d. threading work.
Ideally, it would have a flange so it could be passed through a hole ( not tapped, straight ), and fastened with a standard nut on the opposite side. Then, I would end up threading an eye-bolt through into the internal threading on one side or the other.

That's the other part of the story.
I'll take a step back.
I am starting with 1/4" ABS.
My end goal is to have an eye-bolt ( say 10-32 ) protruding from the "top" side of the ABS. Whatever hardware is on the other side needs to be flush ( a slight flange is fine ).
The side with the eye-bolt needs to be "clean" looking. Just the loop of the eye-bolt, and possibly a nut to lock it down.
Was thinking a typical threaded insert, with knife-threads on the outside, would work. They don't seem to come in 1/4" length, however.
Any other ideas on how to make this work?
Thanks for all your responses.

Never considered that.
Sounds expensive. I'll need 500 pieces, actually.
RE: Am I looking for a "threaded insert"?
What loads are involved?
Could you let the Eye-bolt ring pull up against an outer washer:
Eye-bolt
Washer
ABS (clearance hole)
Washer
Nut
RE: Am I looking for a "threaded insert"?
A washer would be fine, but the eye-bolt can't pass "through" the ABS. The opposite side has to be flush. The ABS rests on the floor, on the side opposite the eye-bolt loops.

If you want them cheaper have you thought about some sort of self tapping thread?

How would I bond the weld nut to the ABS? I've heard of using heat or ultrasound, but don't know the details. Would you suggest one of those techniques?

RE: Am I looking for a "threaded insert"?
Eye-bolt
Washer
ABS (clearance hole)
Washer
Nut
You would have
Eye-bolt
Nut
Washer (fits eye bolt shank)
Slightly bigger washer (fits over "weld nut" boss)
ABS (clearance hole) with boss of "weld nut" sticking thru
Flange of "weld nut".

You mentioned 1/4" ABS, are you concerned with deflection upon lifting? If so, could this lifting eye be incorporated into some support component?
RE: Am I looking for a "threaded insert"?
If you contact Groove-Pin they will give you assistance with installing their insert. I would stay with a push-in system if possible due to your quantity. You might find a heating system on the surplus market. Ultrasonic insertion is prohibitively expensive and please don't think surplus.
For a good cross section of whats available in the insert market take a look at this site. Look at the Microbarb,

In light of that, it sounds like the push in method might work. I was worried about the strength of that method, but our loads are low, so it might work.
Regarding the keenserts, Kaynarguy... I'm not sure I understand them. What are they two tabs for? Installation? They seem a lot like a typical knife-threaded self tapping type.

The commercial versions (Keyserts) that may be best for you can be seen here;

Try searching for Weatherhead PN. W05465.
I think it is close to what you are looking for, the only problem is that the inside thread are NPT. The outside is straight thread.
Hope this helps, David

It is not threaed on the out side but you could install it as a press fit or rough up the outside and glue it.
