self tapping screws thru gyp board
self tapping screws thru gyp board
(OP)
I have a pump room with a ceiling framed of light gage metal studs and 2 layers of gyp board on the bottom. The mechanical guys are running a 6" pipe below the ceiling. The ceiling is a one hour rated assembly. Can I use a self tapping screw in this situation through the gyp board and into the 16 ga metal stud. The screw through the gyp board is unsupported for 1 1/4". Are they going to have trouble installing the screw? Can I be certain that the screw will obtain its design tensile strength? Thanks.
