I need to drill holes in sheet metal for some bolts. The bolts will go through the sheet metal horizontally. I am a little concerned about the threading causing shear. I have seen hardware where a tube is used around a bolt, something like the following but smaller and much less expensive.



What I need would be sheet-metal quality so quite economical but I just don't know what to call it so I don't know how to search for it.

Photo that you posted looks like a "drill bushing"

A straight smooth bushing for sheet metal ? Never heard of that. But pretty common are threaded inserts for sheet metal. Commonly pressed and crimped into sheet metal. Search "rivet nut". McMaster Carr or many other places. Suppose you could drill out a rivet nut if you really wanted a straight bore.

More info on what your really trying to archive would be helpful.
Without a backing plate anything you try to use to use will flex and cause vibration.

You might have better luck at a store like napa or a farm supply store than a big box hardware store.

Look up Barrel Bolts.

The sleeve insert is threaded and then a bolt screws into the end of it, holding it in place.

I buy them in HD, in the bolts / nuts aisle, they come in many sizes and lengths.

Barrel bolt also interchangeably known as a Sex Bolt



Pop Rivet. Not for something to be disassembled and requires a special tool to install.

And those barrel bolts are not limited to the tapered head screw.

I have used many PAN HEAD screws, the threads are the same, and the Pan Head holds flat stock easily.

Yes, I've also seen them in photo albums to allow the album to be easily disassembled to add pages.

In the photo albums or similar binding tasks, they are called Chicago screws.
They come in various lengths. You can also get various extension rod lengths.
Available at any good office supply.

While they do allow the disassembly/page insertion/replacement, they are also just a good way of binding a lot of paper together. If you are doing a lot of Thick reports, it helps to have a paper drill rather than hole punches.

Got to agree though I've never heard the term Chicago screw. I've heard of paper drills but never seen one.
