Product Overview
100mm Black Drywall Screws for heavy-duty applications requiring exceptional penetration through multiple board layers. 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.
100mm heavy-duty long fixings for deep board assemblies and heavy timber frameworks.
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: 100mm length.
- Box quantity: Supplied in a box of 500 for efficient coverage of high-volume projects.
Applications
- Multi-layer drywall assemblies: Ideal for extra-deep wall systems.
- Timber framing and joists: Strong hold for reinforced wall and ceiling structures.
- Heavy partition walls: Reliable fixing through deep substrate layers.
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.
