ForgeFix’s coarse thread drywall screws are a trade-style fixing for securing plasterboard to timber studs, sitting in the same bracket as other site staples from brands like Unifix and Timco. This is a new box of 200, finished in black phosphate, a common coating for internal drylining work where you want decent corrosion resistance during installation and a surface that takes jointing compounds and paint without fuss.

Who are these screws best for?

If you are fixing standard plasterboard to softwood battens or stud walls, the coarse thread bites quickly and holds well in timber. The 50mm length suits thicker boards, dot and dab over battens, or situations where you need more purchase into the stud, but it can be overkill for thin board on shallow framing.

  • 3.5 x 50mm size, useful when you need deeper anchoring into timber rather than just grabbing the face.
  • Coarse thread, aimed at timber studwork, less likely to spin out than finer threads.
  • Black phosphate finish, typical for indoor drylining, not for exterior or persistently damp areas.
