I purchased the bifold track 21-401, I need to know what screws to use, I have to secure into cement, I do not know what size to get.

Hello,

I tested a few screws in the elongated holes on the ends of the 21-401 track and a #8 screw fits well. With that being said, the length would depend on the size of the installation holes that you make in the cement. You are welcome to look through our selection of fasteners here. Thank you!
