Welcome to Hefei SENOTECH New Materials Co., Ltd, your trusted supplier of high-performance fasteners for industrial construction. Our Drilling Screw for Industrial Construction Wall Cladding is crafted from premium 410 Stainless Steel with a Yellow Zinc finish, offering exceptional corrosion resistance and durability. Designed for quick and reliable installation, these screws are available in full sizes and come with free samples for your evaluation. Whether you need to attach metal panels, insulation, or cladding systems, our screws deliver consistent strength and precision.
- Material Excellence: Made from 410 Stainless Steel — a martensitic stainless steel known for high hardness, good tensile strength, and moderate corrosion resistance. Ideal for environments where strength and durability are key.
- Advanced Surface Treatment: The Yellow Zinc Plating provides an additional protective layer against rust and oxidation, extending service life even in humid or mildly corrosive conditions.
- Self-Drilling Design: Equipped with a sharp, hardened drill point that allows the screw to penetrate steel (up to 12 gauge) and wood without pre-drilling, saving time and labor.
- Full Size Range: Available in diameters from #8 to #14 and lengths from 1/2 inch to 6 inches (custom sizes also available upon request). Perfect for various cladding thicknesses and substrates.
- Reliable Thread Geometry: Deep, sharp threads ensure secure grip and high pull-out resistance. Suitable for both light and heavy-duty cladding applications.
- Hex Washer Head: Provides a large bearing surface for distributing load, with a standard hex shape that fits common power tools for torque-efficient installation.
- Free Samples: We offer complimentary samples to test the quality before placing a bulk order. Simply contact our sales team.

Frequently Asked Questions
-
Q: Can these screws be used on steel framing?
A: Yes, the self-drilling tip can penetrate up to 12-gauge steel without pre-drilling, making them ideal for steel studs and light-gauge frames. -
Q: Is the yellow zinc coating durable for outdoor use?
A: The yellow zinc plating offers good corrosion protection for exposed applications, but for extreme marine or chemical environments, we recommend stainless steel without coating or other finishes. We can advise based on your specific condition. -
Q: What are the available packaging options?
A: We offer custom packaging — small boxes for retail, bulk bags for industrial use, or even color-coded boxes per size. Please let us know your preference. -
Q: How can I get free samples?
A: Simply send an inquiry via our B2B platform page or email. We will provide free samples for up to 5 different sizes; you only pay the shipping cost (or we can arrange low-cost shipping). -
Q: Do you provide custom lengths or diameters?
A: Absolutely. Our production line supports full sizes as standard, but we also accept custom dimensions for large-quantity orders. Minimum order quantity for custom sizes is negotiable. -
Q: What is the typical lead time for bulk orders?
A: For standard sizes and quantities (e.g., 50,000 pcs), lead time is 15–25 days after deposit. Custom orders may require 30–40 days. We always confirm the schedule during your inquiry. -
Q: Are these screws suitable for wood cladding?
A: Yes, the self-drilling point works well in wood, and the sharp threads provide excellent grip. The hex washer head also prevents pull-through in softer materials. -
Q: Can I get a test report or certificate for the material?
A: We can provide a mill test report for the 410 stainless steel batch and a salt spray test report for the zinc coating upon request. These documents are available for your quality assurance.
