I am trying to fix my son's scooter and need a 2nd one of these:
I've never seen this style of bolt/screw before: only the first 1/4" or so is actually threaded and the rest is just an unthreaded shaft. Hex/allen wrench fitting at the top.
Can someone help me identify what type of bolt/screw this is so I can order another one?
For neatness you could consider the use of a carriage bolt through from one side of the wood "pivot" point and then put a flat washer and a nyloc nut on from the other side. The parts look like this:
Carriage bolt - The square part under the rounded head keeps the bolt from turning in the wood.
Flat Washer - This keeps the nut from digging into the wood.
nyloc nut - This special type nut has a nylon insert that keeps the nut from loosening and spinning off the bolt.
This is a specialty bolt made up my the manufacturer of the basketball hoop. I suspect you are asking because you need a new one. I doubt if you will be able to find one, but you should be able to make up something very similar that will do the same function. Get a regular bolt, washer and nut, with the right diameter and length. A second washer might be good enough to sandwich in the the square bar to the frame. If not, get a small plate and drill a hole in it for the bolt. The plate will serve the same purpose as the "leg" on the existing bolt.

It is called a shoulder bolt. You will probably need to try a specialized hardware supplier. In the US, Fastenal or McMaster-Carr come to mind as far as national outfits.
With this type of hardware, it is sometimes so specialized to the item it came off of, it could be easier to just locate the manufacturer and model of the scooter. You could then first search online for parts diagrams and part numbers for that, or call their support number.
