Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Versatile Securing Solutions: Designed for precise fastening in machinery, electronics, and structural applications, featuring cross-recessed heads compatible with screwdrivers for secure torque application.
  • Metric Thread Compatibility: Available in standard thread sizes (M2 to M6) to meet national metric specifications, ensuring seamless integration into diverse mechanical systems.

Key features

  • 1. Corrosion-Resistant Brass Material

    • With a brass body and galvanized finish, these screws ensure long-lasting durability in humid or chemically exposed environments. Their corrosion resistance outperforms uncoated steel screws*, making them ideal for outdoor or industrial applications.

  • 2. Secure Cross-Recessed Design

    • The cross-recessed head provides a precise grip with a screwdriver, reducing slippage compared to standard Phillips heads. This design enhances control during installation and removal, minimizing tool wear.

  • 3. Versatile Metric Thread Compatibility

    • Featuring thread sizes from M2 to M8 and lengths ranging from 4mm to 50mm, these screws accommodate a broad range of projects—from delicate electronics (M2/M3) to heavy-duty machinery (M6/M8). Their metric standard ensures universal fitment across global tools.

  • 4. Multi-Use Pan Head Aesthetic & Functionality

    • The flat pan head sits flush with surfaces for seamless integration in visible applications (e.g., furniture, appliances), while the robust brass construction supports structural loads. The pre-set size variety (40+ options) simplifies project planning compared to single-size screws.

  • 5. National Metric Standard Compliance

    • Manufactured to national metric specifications, these screws guarantee precision and interchangeability with standard tools and components. This certification ensures reliability in both DIY and professional settings.
