Product Information

Black Phosphate Coarse Thread Drywall Screws are hardened carbon steel screws which come with an extremely corrosion resistant phosphate finish. It holds self-starting needle point and twin threads for fast fixing of dry lining and plasterboard to timber framing and studs without the need for pre-drilling.

Features

  • Black Phosphate finish for providing increased durability. Proven to withstand 50 hour salt spray test.
  • It has 25 degree Super Sharp (SS) point for ease of penetration.
  • Typically designed for fitting dry linings to timber studding.
  • Generally Coarse-thread drywall screws have slightly greater pull-out strength than fine thread screws.
  • Faster to install due to fewer threads.
  • Designed with Bugle Head which allows the screw to sink effortlessly into the dry lining without the need for countersinking, which in turn minimises the damage to the surface.
  • Made from C10 - 18 Steel.
  • Used for fitting plasterboard, fibreboard, and other types of insulation boards to wood or steel studding.
  • Coarse threads are used when threaded into aluminium or cast iron because the finer threads tend to strip more easily in these materials. 
  • They are stronger when assembled with lower strength nut or tapped hole materials
  • Bugle head minimizes damage to the surface enabling a smoother surface finish.
  • Predominantly used when fitting plasterboard to timber stud work.
