Description

Designed for direct metal-to-metal fastening without the need for pre-drilling, this Daggerz Self-Drilling Metal Screw with High Hex Head and zinc finish delivers dependable performance and ease of use. The high hex washer head offers excellent driving stability and helps seal the connection, while the fine threads ensure superior holding power. With a sharp self-drilling point and a clean zinc-plated finish suited for dry interior metal applications, this screw is a reliable choice for professionals and DIYers alike.

Key Features

  • Self-Drilling #3 Point: Eliminates the need for pre-drilling into steel substrates.
  • High Hex Washer Head: Provides excellent tool engagement and a secure, flush fit.
  • Fine Machine Threads: Deliver reliable grip and holding strength in steel-to-steel applications.
  • Zinc-Plated Finish: Bright appearance and corrosion resistance for dry interior environments (not for exterior use).

Applications

  • Fastening metal panels, steel framing, studs, and brackets in interior construction settings.
  • Ideal for HVAC installs, mechanical fastening, and steel-to-steel fabrication tasks.
  • Suited for commercial or residential interior use where speed and strength are essential.

Installation

  1. Choose a screw length and diameter that ensures full penetration into the steel backing and proper thread engagement.
  2. Use a hex driver bit (e.g., 5/16") with a power tool set to around 2,500 RPM for efficient drive speed.
  3. Drive perpendicular to the steel surface until the washer head seats flush. Avoid overdriving to prevent stripping or surface damage.
  4. Confirm that the zinc coating is appropriate for the application (dry, interior only).
  5. Follow proper spacing and pattern based on the type of connection and structural requirements.

    The Right Point for Every Project

    Different point types pierce various materials. Standard points handle light- to medium-gauge metal, long points tackle thicker steel, self-piercing points work well in wood or thin metal and winged points clear softer layers before drilling harder substrates, ensuring faster, cleaner and secure installations.
