Product Overview

38mm Black Drywall Screws for fixing thicker or denser plasterboard to timber framing. Each screw is manufactured from hardened carbon steel with a black phosphate coating that provides light corrosion resistance and a clean, low-glare finish.

The bugle head ensures a smooth, flush seating without tearing the board’s paper surface, achieving a professional, ready-to-fill finish. 

A sharp W-type gimlet point allows easy penetration and rapid engagement into timber, reducing driving effort. The coarse thread is optimised for wood substrates, delivering strong bite and resistance to pull-out in natural grain.

32mm screws are the most commonly used length for fixing 15mm and high-density boards to timber framing.

Features & Benefits

  • Material: Hardened carbon steel for strength and consistent driving torque.
  • Corrosion resistance: Black phosphate coating resists rust and oxidation under dry interior conditions.
  • Head design: Bugle head compresses gypsum and paper for a flush surface finish.
  • Thread type: Coarse W-type thread offers fast drive and secure grip in timber.
  • Point type: Sharp gimlet point ensures quick starting and reduced splitting.
  • Nominal size: 38mm length.
  • Box quantity: Supplied in a box of 1000 for efficient coverage of high-volume projects.


Applications

  • Thicker plasterboard to timber studs: Ideal for 15mm and high-density boards.
  • Acoustic and moisture-resistant boards: Maintains consistent grip.
  • Ceiling and partition fixing: Ensures strong engagement in wood framing.


Installation Guidance

  • Drive type: Use a Phillips No.2 bit for controlled installation.
  • Speed setting: Drive at medium speed to avoid over-countersinking.
  • Depth control: Seat screw head just below the paper surface without rupturing.
  • Spacing: Maintain 250mm centres on walls and 150mm on ceilings.


Compliance & Performance

  • Manufacturing reference: Produced in accordance with EN 14566 for drywall screws.
  • Finish: Black phosphate coating provides corrosion protection for interior use.
  • Safety: Always wear eye protection and ensure stable support when driving.
  • Important note: Not suitable for exterior or high-moisture environments.
