Hefei SENOTECH New Materials Co., Ltd proudly presents our full-size range of C1022A Carbon Steel Self Drilling Screws with Yellow Zinc Hex Head, engineered specifically for wall cladding applications. As a dynamic trading company since 2020, we have built a reliable global supply chain serving markets across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, and more. Our screws combine cost-effective carbon steel with a durable yellow zinc coating, offering excellent corrosion resistance and ease of installation for both indoor and outdoor cladding projects. Whether you need bulk orders for industrial construction or customized lengths for specific panels, our inventory covers all standard sizes to streamline your procurement.
Key Features & Technical Specifications
- Material: Premium C1022A carbon steel ensures high tensile strength and hardness, ideal for drilling into steel up to 12 gauge (0.105 inch) without pre-drilling.
- Coating: Yellow zinc plating provides moderate corrosion resistance (typically 72-96 hours to white rust in salt spray test), suitable for sheltered or indoor cladding environments. For higher outdoor exposure, optional coatings like stainless steel or hot-dip galvanized are available upon request.
- Head Design: Hexagon head (usually 1/4" or 5/16" hex) allows easy driving with standard hex sockets or impact drivers, reducing cam-out and ensuring consistent torque transfer.
- Self-Drilling Point: Sharp, precision-ground drill tip (e.g., #2 or #3 point) cuts through metal substrates smoothly, saving time and labor.
- Full Size Range: Diameters from #8 to 1/4", and lengths from 3/4" to 3" (or metric equivalents). Custom sizes are available for OEM projects with a minimum order quantity.
| Property | Value |
|---|---|
| Hardness (Rockwell B) | 70-85 HRB |
| Tensile Strength (minimum) | 100,000 psi (689 MPa) |
| Drilling Capacity | Up to 0.105" (2.67 mm) steel |
| Surface Hardness (case) | 550 HV minimum (case hardened) |
| Coating Thickness | 5-15 µm (yellow zinc) |
Customer Benefits
- Time & Labor Savings: Self-drilling design eliminates the need for pilot holes, speeding up installation by up to 50% compared to conventional screws.
- Reliable Fixing: Hex head provides secure grip, allowing high torque application without stripping the drive – critical for metal cladding that endures wind loads.
- Cost-Effective Solution: C1022A carbon steel offers a balanced performance-to-cost ratio, perfect for large-scale projects where budget matters.
- Versatility: Works with steel, aluminum, and wooden substrates (with appropriate point selection). Suitable for wall cladding, roof sheeting, and light steel framing.
- Customizable Options: Different coatings (e.g., black phosphate, zinc-nickel) and packaging (bulk in 25kg cartons or retail poly bags) available to match your supply chain requirements.
