How do I reattach a ceiling fan light shade? One of them is loose and we have a heck of a time changing the lightbulb.
Thanks

Most have 3 or 4 set screws. Where it attaches
To holder.

Stratmando is right for most fixtures. A brand/model would help us be more detailed as would a picture. A few fans I worked on had a ceramic collar that screwed into the fixture to hold the shade but most have the 3 screws as Stratmando points out.

Everything posted above is correct, there are other types as well. Pictures or brand/model would help us narrow it down.
