Evolution Collated Drywall Screws Fine Thread Black Phosphate

Evolution Collated Drywall Screws Fine Thread Black Phosphate are high‑performance plasterboard
fixing screws supplied on collated strips for speedy, consistent installation with auto‑feed
screwdrivers. Designed specifically for fixing plasterboard to light gauge metal studs and
metal ceiling systems, their fine thread and sharp point provide strong holding power and a
clean, professional finish on every drylining job.

Evolution Collated Drywall Screws Fine Thread Black Phosphate are engineered for fast, reliable
fixing of gypsum plasterboard to light gauge steel studs, channels and MF ceiling systems. Supplied
on plastic collated strips, they are ideal for use with compatible collated or auto‑feed screwdrivers,
helping dryliners and partitioning contractors achieve outstanding productivity on site.

The fine thread profile is specifically designed for thin metal framing, gripping securely without
stripping the steel. A sharp, self‑tapping point pierces both the plasterboard and the metal in one
smooth operation, so there is no need for pre‑drilling in standard drywall systems.

The classic bugle head allows the screw to recess slightly below the surface of the board without
damaging the paper face, leaving a smooth, even finish ready for jointing and skimming. The black
phosphate finish reduces friction during driving and provides a level of corrosion resistance suitable
for internal, dry conditions – ideal for partitions, bulkheads and ceilings in residential and
commercial buildings.

Typical Use Cases

• Fixing plasterboard to light gauge metal studs in internal partition walls and corridors.
• Securing ceiling boards to MF or metal grid ceiling systems in offices, schools and retail units.
• Drylining internal walls in new‑build and refurbishment projects using metal framing.
• Forming service risers, duct encasements and shaft walls with plasterboard on steel sections.
• High‑volume drylining work where collated fine thread screws significantly reduce fixing time.

Installation & Usage Tips

• Use with a compatible collated driver: Check your auto‑feed screwdriver suits the strip format and screw length.
• Correct substrate: Fine thread drywall screws are intended for light gauge metal studs and channels, not timber.
• Choose the right length: Allow enough screw length to pass through the board and securely engage the metal stud, following system manufacturer guidance.
• Set depth accurately: Adjust the depth‑stop so the bugle head sits just below the board surface without breaking the paper.
• Follow recommended fixing pattern: Typical guidance (always check the system):
  • Walls: approx. 300mm centres along studs.
  • Ceilings: approx. 150–200mm centres along channels/joists.
• Avoid overdriving: Too much torque will spin out in the metal or tear the board paper; adjust driver settings accordingly.
• Internal dry use only: Black phosphate screws are designed for internal, dry environments. Use more corrosion‑resistant fixings in humid or exposed locations.

Frequently Asked Questions (FAQs)

Common Uses / How to Use

To get the best results with Evolution Collated Drywall Screws Fine Thread Black Phosphate:

1. Confirm your collated screwdriver is compatible with the screw length, gauge and strip type.
2. Load the collated strip into the tool according to the manufacturer’s instructions.
3. Mark the positions of metal studs or channels on the board to maintain correct fixing centres.
4. Hold the plasterboard firmly in place against the metal framing.
5. Present the nose of the screwdriver square to the board and drive the screw until the bugle head is just recessed.
6. Follow the recommended fixing pattern along edges and across intermediate studs/channels.
7. Once all boards are fixed, proceed with joint taping, filling and finishing as per the plasterboard manufacturer’s guidance.
