I don't know much about the difference in threads except that the coarser threads go into wood studs better and the finer threads hold better in steel studs.
There may well be other properties. ----- Original Message ----- From: Gil Laster To: Blind Handyman Sent: Friday, May 01, 2009 9:08 PM Subject: [BlindHandyMan] Drywall Screw Threads Over years I have collected different sizes of drywall screws and just now noticed that most have coarse threads while a few have fine threads including screws of the same style, material, and length. Can anyone explain the purpose or application for coarse threads verses fine threads? - Gil Laster, Charlotte, NC [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
