Our zinc-plated hex head Self-Drilling Screws feature an integrated EPDM sealing washer that delivers superior rust resistance and weatherproof performance—ideal for demanding environments across construction, manufacturing, and infrastructure projects worldwide.

Key Features:

• Zinc-coated steel body ensures excellent corrosion protection in humid or salty conditions
• EPDM rubber washer provides a tight seal against moisture, dust, and vibration
• Self-drilling tip eliminates the need for pre-drilling, saving time and labor
• Hexagonal head design allows for precise torque application with standard tools
• Available in multiple lengths and diameters to suit diverse material types
• Sturdy packaging guarantees safe delivery without damage or quantity discrepancies

These premium-grade fasteners are meticulously crafted using high-quality materials and precision manufacturing techniques. The combination of zinc plating and EPDM washers offers enhanced longevity compared to standard steel screws, making them particularly effective in outdoor applications such as roofing, cladding, metal framing, and structural assembly. Unlike conventional screws that degrade quickly under exposure to environmental stressors, our product maintains mechanical integrity over extended periods—even in extreme climates like coastal regions or industrial zones with chemical exposure.

Ideal for use on wood, sheet metal, composite panels, and other rigid substrates, these hex head self-tapping screws offer exceptional holding power and ease of installation. Their versatility extends beyond traditional building practices—they are widely adopted in shipbuilding, railway engineering, pipeline systems, tunnel support structures, and even aerospace components where consistent performance is non-negotiable. Whether you're working on a commercial rooftop, a steel framework, or a heavy-duty machinery assembly, this screw type provides unmatched efficiency and peace of mind.

Users consistently report satisfaction with the seamless installation process and reliable grip across different surfaces. Many professionals appreciate how the EPDM washer prevents leakage and reduces noise caused by thermal expansion or wind-induced movement—a critical factor in long-term structural stability. Additionally, the absence of thread stripping or loosening over time makes this product a preferred choice among contractors, engineers, and maintenance teams globally.

Frequently Asked Questions:

Can I use these screws on galvanized steel? Yes, the zinc coating ensures compatibility without galvanic corrosion when paired with similar metals.

Are they suitable for marine environments? Absolutely—the EPDM washer and zinc finish provide robust protection against saltwater exposure.

What’s the difference between a self-drilling screw and a tapping screw? A self-drilling screw combines drilling and tapping functions into one step, while a tapping screw requires a pilot hole first.

Do you offer custom sizes or finishes? Yes, we support tailored configurations based on project specifications including length, diameter, and surface treatment options.
