I'm building something and I need a piece of hardware that I'm not sure exists.

Something like this (sorry for the crappy illustration):

Basically I have a length of 5/8" threaded rod that I want to anchor into a beam. I need a cylindrical piece of rod, 3" long that is drilled and tapped to accept the rod. Is there anything off the shelf that I can get that will do this? Or will I have to make something? Any other ideas?

Thanks for letting me pick your brains. :hill:

Search mcmaster.com and see what you can find.

So I am bored and it appears its called something like a cross dowel nut or barrel nut, though I can't find them on mcmaster

Damn. One man's crappy illustration is another man's masterpiece.

Make it your self. Hell it would only take like 5 minutes to make it. I have everything but the 3" piece. But you can pick it up At depot.
But I suppose it all depends on how much they want for it when you find it

This does sound like something where fabrication is the easiest solution easily made, but what is the application. Maybe there is a different solution. Pick my homebuilder brain.

I have seen similar setups of smaller diameter components frequently used for furniture that one assembles at home.

What diameter of 3" smooth rod do you need? Why is the anchor a rod vs. a plate or a threaded insert? (pictured below) What is the load?

True. I could easily just drill a hole and weld a nut on the back of the plate and that would take less time than threading a hole.

So 2 minutes. Lol:dunno::weld:

Yeah, if I had the tools, it would be the easiest solution, but I don't. :o

The application is basically needing to anchor a 5/8 piece of threaded rod into a 3" thick softwood beam so that it can hold weight. I would use a lag, but I don't trust the wood. So, I'm thinking that the drilled/tapped metal rod passing through the beam would help secure the threaded rod. I can't use a plate because there's no clean way to pass it through the beam, and it can't be placed on the top/side becasue of the location. (not sure if that makes sense). :o

Those seem close. I just need a really big one! I'll start searching. thanks. :thumb:

So it has to go threw the 3" piece regardless ?

Buy some rod and bring your threaded rod to the meeting and I'll drill and tap it for you. As Many as needed.

Martin - you know I do much with my junk anymore, and you can come over anytime. I have faced your dilemma before with that situation, and you could jam nut it on each side with either a nylon or rubber bushing, or an aluminum one in galvonic corrosion isn't an issue.

If you're looking for solid rod versus heavy wall tube, you're going to need a really thick piece to have enough meat left on either side of a 5/8" hole. You're talking 1-1/8 to 1-1/2 inch thick dowel. I think I have a piece of the large solid stock left that I made my spare tire carrier pivot on my bumper out of. Let me know if you can't find anything else.

Thanks guys. I'm going to purchase some supplies and then I'll hit you up for some cutting/drilling/welding help. :thumb:

I don't think you will find that "off the shelf". I work in the woodworking industry and all that I've seen are much shorter (like and inch or so) and smaller in overall diameter (such as for 1/4 to 3/8 threaded rod). I think you will be making it from scratch.
