Hex Head Self-Drilling Screws
High-strength fasteners that drill, tap, and fasten in one operation. Designed for heavy-duty metal-to-metal and metal-to-wood connections in industrial construction, roofing, and structural steel applications.
Our Position as a Manufacturer
Anhui Linghong Hardware Technology Co., Ltd. is a China-based Hex Head Self-Drilling Screws manufacturer and supplier with over 20 years of fastener industry experience. We operate a 12,600 m² factory equipped with more than 80 production lines, achieving a stable monthly output of approximately 500 tons. Our hex head self-drilling screws are produced under ISO 9001, ISO 14001, and ISO 45001 certified management systems, with rigorous in-house quality control from first-piece inspection to final ex-factory checks.
We supply standard and custom hex head self-drilling screws for global B2B projects, exporting 40–50 containers to Australia and about 10 containers to Europe and Japan each month. Our engineering team supports OEM/ODM requirements, ensuring that each batch meets your specific dimensional, material, and performance specifications.

We also produce hex head self-drilling screws in stainless steel (SS304, SS316, 410) for coastal or corrosive environments, and in carbon steel with various coatings (zinc, Ruspert, painted) for indoor and outdoor use. Our range includes sizes from #10 to #14 and lengths from 16 mm to 75 mm, with custom dimensions available on request.
Engineering and Configuration Approach
Each hex head self-drilling screw is engineered to meet the demands of your specific joint. We consider the thickness and hardness of the materials to be fastened, the required pull-out and shear strength, and the environmental exposure. Our drill point geometry is designed to penetrate steel up to 12 mm thick without pre-drilling, while the thread form ensures secure engagement and vibration resistance.
We offer several configuration options to match your installation tools and performance needs:
- Head drive: Hex, hex flange, or cross recess for socket, wrench, or screwdriver compatibility.
- Washer assembly: Bonded washers for sealing, EPDM washers for weatherproof roofing, or no washer for clean metal joints.
- Point type: Standard drill point, reduced-tip for thicker steel, or self-drilling with cutting edges for faster penetration.
- Coating/finish: Zinc plating, Ruspert, painted heads (e.g., ivory white, tile red, black), or plain stainless steel.
Quality Assurance and Testing
Our quality management team uses precision instruments, including metallographic polishing machines and Rockwell hardness testers, to verify hardness, case depth, and coating integrity. We perform first-piece inspection, in-process patrol inspection, and final random sampling before packing. Each batch is traceable, and we can provide material certificates and test reports upon request.
We also conduct installation tests to confirm that the drill point performs as expected on representative material samples. This ensures that your production line or construction crew will not face unexpected delays due to fastener failure.
Packaging, Delivery, and Support
We package hex head self-drilling screws in boxes, cartons, or bulk packs according to your specifications. Our export experience ensures that packaging is robust for sea freight, and we can provide palletization and labeling as required. We maintain a stable monthly capacity of 500 tons, so we can handle both large-volume orders and urgent restocks.
Our sales and engineering teams work closely with you from sample approval to final delivery. We provide technical documentation, including dimensional drawings and installation guidelines, to support your project planning.
Information We Use to Configure Your Solution
To prepare an accurate quotation and production plan, please provide the following details:
- Material to be fastened (e.g., steel thickness, aluminum, wood) and its hardness.
- Required screw size (diameter and length) or the specific model number.
- Head style and drive type (hex, flange, cross recess).
- Washer requirement (bonded, EPDM, none).
- Material grade (carbon steel, stainless steel) and coating/finish.
- Quantity per order and target delivery date.
- Any applicable standards (e.g., GB/T 15856.5, Australian Type 3) or performance requirements.
Frequently Asked Questions
Q: Can you produce hex head self-drilling screws with custom lengths and coatings?
A: Yes, we offer custom manufacturing. Provide your required dimensions, material, and finish, and we will produce samples for your approval before mass production.
Q: What is the typical lead time for a container order?
A: Lead time depends on the quantity and customization level. For standard sizes, we can often ship within 2–3 weeks after order confirmation. Custom orders may require additional time for tooling and sampling.
Q: Do you provide test reports or certificates for each batch?
A: Yes, we can provide material certificates, hardness test reports, and coating thickness reports. Our quality system is ISO 9001 certified, and we follow strict inspection procedures.
Q: Are your hex head self-drilling screws suitable for outdoor roofing applications?
A: Absolutely. We offer screws with EPDM washers and corrosion-resistant coatings (e.g., Ruspert, painted heads) specifically designed for roofing and cladding. For coastal areas, we recommend stainless steel grades.
Q: Can you match a specific standard like Australian Type 3?
A: Yes, we produce reduced-tip hex head self-drilling screws that meet Australian Type 3 requirements. We have experience exporting to Australia and understand the relevant specifications.
