As Hefei SENOTECH New Materials Co., Ltd, we are pleased to introduce our premium Yellow Zinc Drilling Screw Flat Head Full Sizes Available C1022A Carbon Steel Bulk Packing. Established in 2020, our trading company has achieved an annual export value of US$1 million to US$1.5 million, serving markets across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and more. These self-drilling screws are designed for quick installation without pre-drilling, offering excellent holding power and corrosion resistance thanks to the yellow zinc plating. Whether you need small quantities for a project or bulk supply for mass production, we offer full size options and free samples to help you test the quality firsthand.
Product Features & Technical Specifications
- Self-Drilling Point: The sharp drill point efficiently penetrates metal substrates (up to 4 mm thick) and wood, eliminating the need for pre-drilling, saving time and labor costs.
- Flat Head Design: Provides a flush finish when installed, ideal for applications where a smooth surface is required, such as metal roofing or cladding.
- Yellow Zinc Plating: Offers good corrosion resistance for indoor and mild outdoor environments, extending the screw’s lifespan. The yellow finish also provides visual identification of plating type.
- C1022A Carbon Steel: Heat-treated to achieve high hardness and tensile strength, ensuring reliable performance even in demanding fastening tasks.
- Full Sizes Available: We stock a wide range of diameters (e.g., #6, #8, #10, #12, #14) and lengths (from 3/8 inch to 6 inches or metric equivalents). Custom sizes can be produced upon request.
- Bulk Packing: Packed in sturdy bulk bags or cartons, ideal for contractors and distributors who require large quantities. Weight per package can be customized (e.g., 25 kg bags or 50 lb boxes).
- Free Samples: Request a sample pack to evaluate fit, finish, and performance before placing a bulk order. Standard samples are sent within 2 business days.

Frequently Asked Questions (FAQ)
-
Q: Can these screws be used for metal roofing?
A: Yes, the self-drilling point and flat head are well-suited for attaching metal roof panels to steel purlins. However, for exposed applications, consider using a sealing washer if water tightness is required. -
Q: Are they corrosion resistant enough for outdoor use?
A: The yellow zinc plating provides moderate corrosion resistance for indoor and sheltered outdoor use. For harsh coastal or chemical environments, we recommend upgrading to hot-dip galvanized or stainless steel variants. -
Q: What sizes are available exactly?
A: We offer diameters #6, #8, #10, #12, #14 and lengths from 3/8 inch up to 6 inches. Metric sizes (e.g., M3.5 to M6.3) and custom lengths can be produced upon request. -
Q: Do you provide free samples? How can I request them?
A: Yes, we provide free samples for evaluation. Simply contact our sales team with your required size and quantity (typically 5–10 pieces per size). Standard samples are shipped within 2–3 working days; you only pay for shipping. -
Q: What is the typical lead time for bulk orders?
A: For stock sizes, lead time is usually 7–15 days after order confirmation. For custom sizes, it may take 20–30 days depending on production volume. We can expedite if needed. -
Q: Are these screws suitable for wood fastening?
A: Yes, the coarse thread works well in wood, plywood, and OSB. The self-drilling point effectively penetrates softwoods and hardwoods without splitting. However, for extremely hard woods, pre-drilling a small pilot hole is recommended. -
Q: What packaging options do you offer?
A: We primarily supply in bulk packaging such as 25 kg woven poly bags, 50 lb cartons, or palletized loads. Retail-ready boxes or blister packs are available for smaller quantities if requested. -
Q: Do you have any certifications for quality?
A: While we do not claim specific third-party certifications unless requested, our products are manufactured under strict internal QC. We can provide mill certificates and test reports upon request for specific orders.
