I have a pair of old metal bifold doors in my house. Unfortunately, the plastic or nylon cap on the top pivot on one of the doors broke. So far I have not been able to find the correct replacement part or a suitable substitute. What is the precise name of this part, so that I can perform a better search and find the part I need?
Things I have tried
- Visited Home Depot. They showed me all their bifold door hardware, but they don't have the right part. I showed the broken part and photos of the unbroken part, and the Home Depot staffer had not seen anything quite like it.
- Tried a different top pivot from Home Depot. In fact, I bought two different types and tried to make them work, but either the metal pivot would not attach to my door, or the plastic cap would not stay in the track.
- Searched the web. I cannot find the exact top pivot that came with my door or even a similar one that has a 1" cap with a lip.
Description of the part I need
The top pivot I need consists of a metal Phillips screw about 1-1/4" long and 3/16" wide that goes inside a plastic or nylon cap about 1" long with a lipped or beveled top. The lip is only slightly wider than the rest of the cap, which is only slightly wider than the metal screw. The purpose of the lip is to stay inside the guide track above the door. The plastic cap slides up and down as needed on the metal screw as the door opens and closes, which keeps the lipped cap inside the track. The screw fastens to a threaded hole on the top of the metal bifold door, so that the lipped cap sticks up from the door and rests in the track to guide the sliding end of the door. The bottom opening of the track is only slightly narrower than the track width, so there's not much allowance for using a different top pivot. Most modern top pivots seem to use a roller that is much wider than the metal part of the pivot, but I can't do that with this track.

My other bifold door has the part I need, and it looks like this:
The top pivot attaches to a threaded mount at the top of the door. The following photo shows that mount from the inside of the door looking up:
These photos show the broken top pivot that I need to replace. Notice that the metal screw is fine but the plastic or nylon cap's lip or bevel has broken off (and I no longer have it, so Super Glue isn't an option):
