I have several nail pops in the ceiling sheet rock of my house and I've decided to finally address/fix them. The house was built 40 years ago so I don't believe there is any underlying issue other than time.
I have a bucket of coarse thread screws left to me from a different project hanging green board in a bathroom and I'd like to use these rather than buy yet more. However, I'm uncertain of the length (1-5/8") for ceiling drywall (which may only be 1/4"?) and the specific details of the screw (see pictures) such as the serrated head, etc.
