Hex Socket Countersunk Head Coarse Thread Chair Screw Confirmat Screw Wood Furniture Euro Joints Screws

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Versatile Fastening: Designed for secure assembly of wood furniture, especially chairs and Euro joints, featuring a countersunk head that sits flush with surfaces for a seamless finish.
  • Coarse Thread Strength: Optimized for wood applications with coarse threads that provide strong grip and stability in porous materials.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With zinc-plated steel and galvanized coating, you can ensure long-lasting durability in corrosive environments, outperforming non-coated screws*. The black oxide and plain finishes further enhance adaptability to different project requirements.

  • 2. Precision-Driven Interactive Design

    • With a hexagonal socket head and flared shank design, you can achieve precise torque control and secure fastening in various materials, unlike slotted or Phillips-head screws. The flared end provides superior grip for stable installations.

  • 3. Versatile Performance Parameters

    • Offering thread sizes from M4 to M10 and lengths from 4mm to 12mm, you can handle diverse material thicknesses and project requirements more effectively than limited-range screws*. The coarse thread ensures strong hold in wood and other porous materials.

  • 4. Multi-Scenario Solutions

    • Designed for furniture assembly and industrial applications, these screws provide a sleek, flush finish while maintaining structural integrity in both home and commercial settings, surpassing general-purpose screws*. The countersunk head ensures seamless integration into surfaces.

  • 5. Global Compatibility & Customization

    • With metric and inch measurement systems and customizable sizes/thread pitches, you can adapt to international standards and specific project needs, offering greater flexibility than non-adjustable screws*.

Product details

Hex Socket Countersunk Head Coarse Thread Chair Screw Confirmat Screw Wood Furniture Euro Joints Screws

The Hex Socket Countersunk Head Coarse Thread Chair Screw is engineered for robust fastening in wood furniture and industrial applications.

Supplier's note

  1. Breakthrough Features:

    • Zinc Plating: Outperforms uncoated steel by 20% in salt-spray tests, ideal for marine furniture.
    • Hex Socket Head: Enables 15% tighter torque control vs. slotted heads, reducing slippage.
    • Flared Shank: Improves pull-out resistance by 25% in softwoods.

  2. Version Selection Guide:

    • Base Model: Perfect for indoor furniture assembly (e.g., office chairs) where basic corrosion protection suffices.
    • Advanced Model: Recommended for outdoor decking or machinery where epoxy coating and heat-treated threads prevent rust and wear.
    • Pro Model: Tripling industry-standard corrosion resistance, this version is critical for offshore equipment or humid industrial settings.

With the Pro Model’s triple-layer coating and stainless core, you can fasten metal joints in saltwater environments without risk of rust. The Advanced Model’s heat-treated threads ensure longevity in high-vibration machinery. Choose the Base Model for cost-effective indoor applications.
