These self drilling drywall screws are designed specifically for fixing plasterboard to metal wall and ceiling track systems. The No.2 drill point bores cleanly into steel sections up to 2.0mm thick without the need for pre-drilling, which makes a real difference when you are working through a full run of studs and track. Each screw carries a Fire Classification of A1, making them suitable for use in fire-rated partition and ceiling systems where specification matters.
The bugle head profile is what sets a proper drywall screw apart from a standard countersunk fixing. Rather than cutting aggressively into the board face, the bugle shape bears the load gradually as the head seats, reducing the chance of breaking through the paper facing. Get the depth right and the head sits just below the surface, ready for a thin skim of finish without tearing the board. A flat-headed screw on a plasterboard job is the kind of shortcut that shows up at decoration stage.
Self Drilling Drywall Screws: Sizes and Applications
The range covers ten sizes from 3.5 x 25mm through to 4.8 x 125mm, which means you are covered for everything from lightweight 9.5mm board on a metal ceiling grid to double-layer 15mm board on a heavy-duty partition. The smaller diameters handle standard single-layer boarding on light gauge track. The larger sizes in the 4.8mm diameter range are better suited to fixing through thicker board assemblies or into heavier steel sections where more thread engagement is needed.
All screws in this range use a Phillips No.2 recess. This is the near-universal standard for drywall work and matches the No.2 drywall bit fitted in most screw guns and auto-feed tools. The drive geometry gives a positive engagement without the cam-out issues you get when forcing an incorrect bit into a stripped recess halfway up a scaffold board.
Box Quantities
Box quantities run from 100 up to 1000, so whether you are pricing a small domestic job or ordering for a full commercial fit-out, there is a pack size that keeps your cost per screw sensible. On larger projects, buying in 1000-screw boxes makes a material difference to cost and means fewer trips to the van.
The zinc plating gives adequate corrosion resistance for interior dry-lining work. These self drilling drywall screws are not intended for exterior or wet-area applications, but for everything inside a finished building they will perform reliably over the long term. Zinc-plated fixings also tend to be more sympathetic to drywall bits than case-hardened alternatives, which reduces bit wear across a long shift.
Pro Tip: When using an auto-feed screw gun, set the depth clutch on a scrap piece of board first so the head seats consistently without breaking the paper facing, as under-driven screws will telegraph through finish plaster and over-driven ones weaken the board around the fixing.
Self drilling drywall screws are used throughout the dry-lining and partition trades for fixing plasterboard to metal stud and track systems. This includes internal partition walls, suspended ceiling grids, shaft wall systems, and fire-rated enclosures. The self-drilling point removes the pre-drilling step, which keeps work moving on large-scale boarding jobs where you might be driving hundreds of screws per hour.
They are used by dry-lining contractors, general builders, interior fit-out teams, and partition system installers on both domestic and commercial projects. Sizes up to 4.8 x 125mm are commonly used for double-layer boarding on acoustic or fire-rated assemblies where increased screw length is specified to achieve the required pull-out resistance through both board layers and into the steel section behind.

Not suitable for: These screws are not suitable for fixing into timber studwork or solid backgrounds where a coarse-thread drywall or woodscrew would be the correct choice. The self-drilling point is rated for metal sections up to 2.0mm thick only and will not perform correctly in heavier gauge steel.
Select the correct screw length based on the board thickness plus the required penetration into the metal section behind. As a general guide, the screw should pass fully through the board and engage the steel by at least 10mm. For single 12.5mm board onto standard 0.5mm track, a 3.5 x 25mm screw is typically sufficient. For double-layer or thicker board, move up in length accordingly.
Use a dedicated drywall screw gun or a variable-speed drill with a depth-stop collar set to the correct depth. Drive each screw so the bugle head dimples just below the board surface without breaking the paper face. Screws that sit proud will cause problems at the taping and finishing stage. Screws driven too deep weaken the board at that point and may need an additional fixing alongside.
Mark your screw positions at the correct centres, typically 150mm to 200mm apart depending on the specification.
Set the depth clutch or collar on your screw gun using a test piece of the same board before starting the run.
Position the screw tip onto the board face at the marked location and over the stud or track behind.
Drive the screw at a steady speed, allowing the self-drilling point to penetrate the metal section cleanly.
Check that the bugle head sits just below the board surface without tearing the paper facing.
If a screw is over-driven or strips, drive a fresh screw 50mm away from the failed fixing rather than reusing the same hole.
What is the maximum steel thickness these self drilling drywall screws will drill into?
The No.2 drill point is rated for steel sections up to 2.0mm thick, which covers the light gauge track and stud used in standard dry-lining systems. For heavier gauge steel, you would need to pre-drill or use a screw with a higher drill point rating.
Can I use these screws for fixing plasterboard to timber studwork?
No. These are designed for metal track systems. For timber studwork, you need a coarse-thread drywall screw, which has a more aggressive thread profile to grip wood properly. Using a fine-thread self drilling screw in timber will give poor pull-out resistance.
What does the A1 Fire Classification mean for these drywall screws?
A1 is the highest fire classification for construction products under EN 13501-1, indicating the material does not contribute to fire. This makes these screws suitable for use within fire-rated partition and ceiling assemblies where fixings are specified to meet a particular fire performance standard.
These zinc-plated self drilling drywall screws are manufactured with a hardened steel core to allow the No.2 drill point to cut cleanly through light gauge mild steel track without pre-drilling. The fine thread pitch is optimised for metal engagement, and the bugle head geometry distributes load across the board face to minimise surface damage. Fire Classification A1 in accordance with EN 13501-1 confirms the zinc-plated steel fixing contributes nothing to fire load, meeting the requirements of fire-rated dry-lining system specifications.
