This is for a bifold door. I want to have front and back knobs using the same screw.

I can’t recall what this assembly is called nor the screw name.

  • The knob on the inside may keep the door from opening as far as it could otherwise. The knobs do not necessarily need to be connected. ( on the same plain)

  • I think I will get double ended screws. It’s ok not to have the dorms open flush. I appreciate your answer.

I don't ever recall seeing a "kit" for this. When I've had to do it, I just got the two knobs and cut the head off one of the screws. If the screws that came with the knobs were too short, then I got a longer screw and cut the head off. There are double threaded studs out there but they are usually too big for what you want to do.

  • Your comment helped me to find double ended or dowel screws.

Just use a

no-head bolt

and buy two handles.

Probably want about 2 1/2" length (although depends on size of handles)

    No head bolt, Also called Threaded Rod. Finding it with the correct threads for a door handle may be tricky.?? Depending on the knobs.

  • What I usually do is bring the item I'm threading (the knob) with me to Home Depot or Lowes and try until I find the right bolt. (unless you can find the thread pitch labeled somewhere on the knob.)

  • I think AM's point is that you need opposing thread direction on each end. The threads would be backward for one side.
