Zinc Plated Countersunk Flat Head Self-Drilling Screw – Stepped Collar & Winged Tip

Product Overview

Our Zinc Plated Countersunk Flat Head Self-Drilling Screw combines speed, durability, and precision for fastening metal sheets, wood, and composite materials. Featuring a stepped collar to prevent over-drilling and a winged tip for rapid pilot hole creation, this screw eliminates the need for pre-drilling, reducing labor and tooling costs. Ideal for roofing, HVAC, and construction projects, its zinc-plated finish ensures corrosion resistance and long-term reliability in harsh environments.


Key Features

✅ Self-Drilling Winged Tip

  • No Pre-Drilling Required: Winged tip drills a clean pilot hole, while the stepped collar ensures consistent depth control.
  • Fast Installation: Saves time in high-volume projects like metal roofing or framing.

✅ Zinc Plated Finish

  • Corrosion Resistance: Trivalent zinc coating protects against rust, humidity, and mild chemicals.
  • Durable & Cost-Effective: Budget-friendly alternative to stainless steel for indoor/outdoor use.

✅ Countersunk Flat Head Design

  • Flush Finish: Sits level with surfaces for a professional look and reduced snagging.
  • Wide Bearing Surface: Distributes load to prevent material deformation.

✅ Stepped Collar

  • Depth Control: Prevents over-penetration in thin-gauge metals or brittle substrates.
  • Grip Enhancement: Improves clamp force by compressing material under the collar.

✅ Carbon Steel Construction

  • Grade 4.8/8.8: Tensile strength up to 800 MPa for structural integrity.
  • Reusable: Maintains thread sharpness for multiple installations.
