Knauf Drywall Screw 1000/Box - 3.5MM X 35MM

Diameter: 3.5 mm, length: 35 mm, head type: large head, finish: zinc-plated, quantity: 1000 screws per box. Suitable for interior drywall applications on wood or metal studs.

Yes. The 3.5x35 mm drywall screw is designed to securely fasten drywall to both wood and metal studs, providing a strong hold in typical interior installations.

Drive the screws perpendicular to the drywall surface with a drill/driver set to an appropriate torque. Let the screw head sit slightly below the surface without over-tightening to avoid dimpling or tearing the drywall.

Yes. The zinc-plated finish provides basic corrosion protection for interior dry environments. They are not intended for exterior or high-moisture conditions.

Wear eye protection to guard against metal shards, keep screws organized to prevent puncture injuries, and store them in a dry place to maintain coating integrity.

They’re ideal for interior drywall installations such as wall partitions, ceilings, and room renovations where drywall needs to be securely attached to studs.

For different project needs, you can consider these alternatives on Fepy: Knauf Drywall Screw 3.5x25mm (https://fepy.com/product/knauf-drywall-screw-3-5x25mm) and Knauf Drywall Screw 3.5x50mm (https://fepy.com/product/knauf-drywall-screw-3-5x50mm). The 25 mm variant is shorter for lighter runs, while the 50 mm variant offers extra length for thicker assemblies. A 4.0x35mm option (https://fepy.com/product/knauf-drywall-screw-4-0x35mm) provides slightly different holding characteristics for heavier drywall loads.

A standard drill/driver with an appropriate bit (Phillips or Pozidriv, depending on head type) works well. Use a clutch to avoid overdriving and reduce the risk of damaging the drywall or studs.

The 1000 screws per box offer cost efficiency and fewer mid-project restocks, while Knauf’s zinc-plated design provides reliable performance for interior drywall applications with consistent holding power.

Drive the screw until the head is flush with the drywall surface, then stop. Avoid sinking the head too deep, and ensure the drill/driver maintains steady, moderate pressure to prevent tearing the paper or over-penetration.

Keep them in a dry, cool place away from moisture. Use original packaging or sealed containers to prevent rust on the zinc coating and to keep the screws organized for quick access during a project.
