Help Locating Name of Fastener

[haured]

I would appreciate any help in locating the and even a source for a specialty fastener. The fastener is a like T-nut that with external and as well as internal threads. They would be used as an alternative to a pop rivet threaded insert. To use one you drill a hole in sheet metal, insert the T-nut and then put a hex nut on the external thread. The internal threads are then used to bolt on the second piece of material in place. I found one in a scrap yard that was used in the aluminum frame for an RV tarp.

With any luck I have attached pictures of the one fastener that I have. Number 1 shows it completely disassembled; Number 2 is assembled with a nut on the exterior thread and a cap screw screwed into the internal thread.

Any help in locating the name or source of these would be greatly appreciated.

that almost looks and acts like a bulkhead to me

although most bulkheads are for plumbing applications, not structural. As such they are usually made of plastic type materials. Mcmaster does have some stainless ones but they start at $80 each and go up to over $300

Sounds like it could be some sort of standoff. Although it could be a specialized fastener just for the company that made the tarp & frame.

Could be a bulkhead connector, but those are typically larger and the ID would be threaded for pipe.

It looks like a type of threaded insert, but with a backer. Most threaded insert install from the front, into a blind hole, or at least into something where there is no rear access, but that clearly installs from the rear.

Did that come off an appliance like a washer and have a leveling foot screwed into it?

You can make a similar one if you have a drill press and a tap.

Get a piece of "all thread", the correct OD, cut it to length and drill and tap a hole through it. Put a nut on the front and back. I would add a drop of thread locker to the back nut.

Check your local RV shop, or try Lawson Products.

That looks like a bolt that was modified for a special use. How many do you need? real simple job for a lathe.

Thanks for all the responses. I do not really need any of these fasteners at the moment. As suggested I have once in the past modified a T-nut to do the same thing. When I found this unusual fastener I thought it would be interesting to know where to find them if ever needed again. Also as suggested it may be a custom fastener. When I have a chance I'm going to stop by a major RV supplier and see if they have any idea. If I find out anything further, I will certainly post the info. Again thanks for all the ideas.
