I bought this self drilling dyrwall anchor https://www.lowes.com/pd/E-Z-Ancor-50-Pack-1-5-8-in-x-1-2-in-Dia-Standard-Drywall-Anchor-Screws-Included/1098803 Our curtain is very long and we wanted to place the bracket 2 inches from the ceiling. I first tried the hole at the top but it was stuck in the middle. Then I used the drill bit and it couldn't penetrate either. Not sure what is behind it and doesn't feel like a stud. Next I used the drill bit on the two holes below and they were penetrated easily. However, the anchors still couldn't go all the way in as shown in the picture. Now I have patched the holes. The only thing I can think of is the root of anchors being too wide and it's where they got stuck. But in the youtube videos, they went in pretty easily. Does anyone know how to deal with this issue?
I believe you’re trying to set those into the wooden top plate of your wall.
If you had any wood shavings while drilling, just use a long (>3”) wood screw.
Those anchors are fine, but are for hollow plaster walls. If you are truly in empty space on the lower holes, you might just need to push harder to engage the threads while spinning it in.
