Screw for bi folding door. The screw locks the hardware in place. Used to adjust the edge of the door to the wall.

Thanks for reaching out! We, unfortunately, do not sell a screw with the specifications you are looking for. 

Bifold parts are very particular, so I can't guarantee that you will be able to locate an exact replacement. However, I recommend visiting a local hardware store. You might have better luck getting information on where you can find a replacement for this.

I apologize we can't be of more help!
