Rust-proof Knauf Phillips Coarse Thread Drywall Screw 41x28 cm

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Drywall Installation: Designed for secure attachment of drywall to wooden studs or structural elements, featuring a sharp tip for easy penetration without pilot holes.
  • Versatile Thread Options: Equipped with both coarse and fine thread types to accommodate varying material densities and project requirements.

Key features

  • 1. Material Technology

    • With phosphate and zinc-plated steel, you can achieve superior rust resistance compared to standard steel screws*. The dual-layer coating protects against corrosion, ensuring durability in humid or harsh environments.

  • 2. Interactive Design

    • With a Phillips drive and bugle head design, you can ensure precise installation and seamless surface finishes. The Phillips head provides secure grip during driving, while the bugle head sinks flush with drywall for a clean appearance.

  • 3. Performance Parameters

    • With coarse thread design, you can penetrate drywall quickly without pilot holes, saving installation time*. The sharp tip and aggressive threading reduce effort and improve efficiency for faster project completion.

  • 4. Scenario Solutions

    • Designed for drywall applications, you can securely attach materials in both home and commercial environments. The screws accommodate diverse projects, from residential wall installations to heavy-duty commercial setups requiring strong, long-lasting holds.

  • 5. Customization & Compatibility

    • With coarse and fine thread options and metric/inch measurement compatibility, you can adapt to varying material thicknesses and global project requirements*. The versatile design ensures seamless use across different materials and construction standards.

Customization guide

Adjustable parameters include:

  • Thread Type: Choose coarse for quick installation in soft materials or fine for precision in dense materials.
  • Length: Customize lengths beyond 150mm for thicker substrates.
  • Finish: Opt for additional coatings (e.g., black oxide) for aesthetic or harsh-environment use.

Get inspired

With a bugle head design, you can install drywall panels seamlessly without pre-drilling. The rust-proof finish ensures longevity in humid environments, while the Phillips drive allows effortless torque control. Pair coarse threads with lightweight materials for faster assembly and fine threads for reinforced joints.

Supplier's note

  1. Technical Breakthroughs:

    • Dual Coating System: Combines phosphate and zinc plating for 2x longer corrosion resistance than single-layer finishes.
    • Bugle Head Design: Reduces cracking in drywall by 40% compared to flat heads.
    • Adaptive Thread Options: Pro model’s dual threads enable 20% faster installation in mixed-material projects.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard drywall installations (e.g., residential walls).
    • Advanced Model: Best for contractors needing adjustable lengths and corrosion resistance in coastal areas.
    • Pro Model: Engineers handling heavy-duty projects (e.g., commercial partitions) benefit from its extreme torque and thread versatility.

With the Pro version’s triple-certified chemical resistance, you can safely fasten moisture-exposed drywall in bathrooms or kitchens. Pair its fine thread with steel studs for a 30% stronger hold than coarse-thread alternatives.
