I recently purchased some 2nd hand outdoor furniture. It is missing a couple of connecting bolts, like the one pictured below, and I want to purchase replacements.
The bolt is used to connect two pieces of folding chair arm that rotate against each other, hence the smooth section in the middle which matches the diameter of the hole.
I had a quick look around and didn't find anything exactly like it.
My problem is finding the right name for this type of bolt so I can make a more targeted search.
I think the bolt has screw threads at each end, but I was only able to remove the nut/cap at one end - I guess whichever one is looser, then there is nothing to grip to undo the other end.
The bolt has a "shoulder" in the middle.
I found "furniture connecting bolts" which are like a single-ended version of this, with the same flattened hex nuts.
I found "shoulder bolts" again single-ended but with thicker headed nuts.
I found double-ended "threaded rod" without the shoulder.
Any help with naming this bolt would be much appreciated!
