READ MOREAnhui Linghong Hardware Technology Co., Ltd. is a China-based manufacturer and factory specializing in wafer head self-drilling screws. Our range is designed for light-gauge steel construction, sheet metal fastening, and thin-panel applications where a low-profile head and integrated drill point deliver one-step installation. With over 80 production lines and a monthly capacity of 500 tons, we supply standard and custom configurations to distributors, contractors, and OEMs across Australia, Europe, Japan, and beyond.
Our wafer head self-drilling screws combine a wide, flat head with a self-drilling point, eliminating pre-drilling and reducing installation time. The head's large bearing surface distributes clamping force evenly, preventing deformation or tearing of thin materials like gypsum board, galvanized steel, and aluminum panels. We offer these screws in carbon steel with anti-corrosion zinc plating, and we support custom sizes, drives, and packaging to match your project requirements.
Product range: Cross recess (Phillips) and square drive wafer head self-drilling screws, available in sizes such as 10-16x16-55, 10-16x16-30, and 10-24x16-30, with custom lengths and thread configurations on request.
These screws are engineered for fastening thin materials to light-gauge steel substrates up to 2.5 mm thick. Typical applications include:
The wafer head's low profile ensures no protruding bumps after installation, allowing direct skim coating or painting over the fastener. This makes them ideal for decorative finishing projects where aesthetics matter. The integrated drill point is hardened to penetrate steel without separate drilling, and the Phillips or square drive ensures positive bit engagement under high-torque power tools.
| Specification | Typical Value | Notes |
|---|---|---|
| Material | Quenched carbon steel | High hardness for drilling |
| Surface treatment | Zinc plating (yellow, blue, or clear) | Corrosion resistance |
| Drilling capacity | Up to 2.5 mm steel | Light-gauge steel and sheet metal |
| Drive types | Phillips (cross recess) or square drive | Custom drives available |
| Head profile | Ultra-thin, wide flat wafer head | No washer needed |
Our quality control includes first-piece inspection, in-process checks, and final ex-factory testing. We use metallographic polishing machines and Rockwell hardness testers to verify case depth and core hardness, ensuring consistent drill point performance and holding power across every batch.
We understand that each project has unique fastening requirements. Our wafer head self-drilling screws can be customized in several ways:
For high-volume projects, we can also produce collated screws for use with auto-feed screwdrivers, improving installation speed on large-scale framing or cladding jobs.
Our screws are designed for compatibility with standard power tools and auto-feed systems. The consistent head geometry and drive depth ensure reliable feeding and seating, reducing downtime on assembly lines. For manual installation, the sharp drill point and optimized thread design minimize driving torque, preventing cam-out and operator fatigue.
We provide technical guidance on recommended drill speeds, torque settings, and fastener spacing based on your specific material stack-up. Our team can also assist with installation trials to validate performance before full production.
As a certified manufacturer, we operate under ISO 9001 for quality management, ISO 14001 for environmental management, and ISO 45001 for occupational health and safety. These certifications reflect our commitment to consistent product quality and responsible manufacturing practices.
Every batch undergoes rigorous inspection, including dimensional checks, hardness testing, and salt spray testing for coating performance. We maintain full traceability from raw material to finished product, allowing us to provide documentation and test reports upon request.
Wafer head self-drilling screws are designed for permanent installation, but we support our customers with spare parts and technical advice for any application challenges. Our experienced team can recommend the correct fastener grade and coating for corrosive environments, and we offer after-sales support to address any field issues.
We maintain a complete packaging system and an experienced logistics team to ensure safe delivery. Our export experience includes regular container shipments to Australia, Europe, and Japan, and we can adapt packaging to meet your regional standards.
To prepare an accurate quotation and configuration, we need the following project details:
With this information, we can recommend the most cost-effective solution and provide samples for testing before mass production.
Our standard wafer head self-drilling screws can penetrate light-gauge steel up to 2.5 mm thick. For thicker materials, we recommend using a larger drill point or a different fastener type.
Yes, we offer custom sizes, drive types, and coatings. Provide your specifications, and we will produce samples for your approval before mass production.
No, the integrated drill point eliminates the need for pre-drilling, saving time and labor. This is a key advantage of self-drilling screws.
We offer bulk packaging, retail boxes, and custom labeling. For collated screws, we provide plastic or paper strips suitable for auto-feed tools.
We follow ISO 9001 procedures, with first-piece inspection, in-process patrol checks, and final testing. We use Rockwell hardness testers and metallographic equipment to verify material properties.
Lead time depends on quantity and customization. For standard sizes, we can often ship within 2-3 weeks. Custom orders may require additional time for tooling and sampling.
Our portfolio also includes Products, Wood Screw, Carbon Steel Wood Screws for applications with different operating ranges, interfaces or integration requirements.
