Corrosion-Resistant Wood Fasteners Built for Demanding Environments
We are a China-based stainless steel wood screws manufacturer and supplier, producing a full range of 304 (A2) and 316 (A4) stainless steel wood screws for timber construction, outdoor structures, marine applications, and furniture assembly. Our screws are engineered with coarse threads, sharp points, and optimized geometry to deliver strong pull-out resistance and reliable performance in damp, coastal, or chemically treated wood environments.
With over 80 sets of production equipment and a stable monthly capacity of 500 tons, we supply standard and custom stainless steel wood screws to distributors, project managers, and OEMs across Australia, Europe, Japan, and North America. Our factory operates under ISO 9001, ISO 14001, and ISO 45001 certified management systems, ensuring consistent quality from raw material to finished batch.

Material Selection: 304 (A2) vs. 316 (A4)
We offer both 304 (A2) and 316 (A4) stainless steel grades. 304 provides excellent corrosion resistance for most outdoor and damp environments at a cost-effective price. 316 adds molybdenum, significantly improving resistance to chlorides, salt spray, and seawater, making it the preferred choice for coastal projects, docks, and applications involving treated wood.
Application Fit and Engineering Considerations
Our stainless steel wood screws are designed to handle the expansion and contraction of wood without loosening. The coarse, deep threads provide strong grip in softwoods and medium-hardwoods, often eliminating the need for pre-drilling. For hardwoods or dense engineered wood, we recommend selecting a screw with a sharp point and optimized thread angle to reduce driving torque.
When selecting a screw for your project, consider the following:
- Wood type and density – affects thread design and point type.
- Exposure conditions – indoor, outdoor, coastal, or chemically treated.
- Load requirements – pull-out and shear strength needed.
- Installation method – manual or automated driving tools.
- Head style – countersunk for flush finish, truss or pan for exposed applications.
Quality Assurance and Testing
We maintain strict quality control throughout production. Our quality team performs first-piece inspection, in-process patrol inspection, and final ex-factory inspection on every batch. We use precision instruments such as metallographic polishing machines and Rockwell hardness testers to verify material structure and hardness, ensuring consistent mechanical properties.
Our quality management system is certified to ISO 9001, and we also hold ISO 14001 (environmental) and ISO 45001 (occupational health and safety) certifications. This reflects our commitment to producing reliable fasteners while maintaining responsible manufacturing practices.
Customization and Project Support
As a manufacturer, we support custom stainless steel wood screws tailored to your drawings or performance requirements. We can adjust dimensions, head styles, drive types, thread forms, and packaging to suit your assembly lines or distribution needs. Our engineering team works with you to confirm the correct configuration for your application.
We also offer a range of related fasteners, including Carbon Steel Wood Screws, Self-Drilling Wood Screws, and Stainless Steel Self-Tapping Screws. This allows you to consolidate your fastener sourcing with one supplier.
Information We Use to Configure Your Solution
To prepare an accurate quotation and technical proposal, we need the following project details:
- Material grade (304 or 316) and any specific corrosion resistance requirements.
- Dimensions: diameter, length, head style, drive type, and point type.
- Wood type and thickness, plus whether pre-drilling is planned.
- Quantity per order and annual volume forecast.
- Packaging preferences (bulk, retail, collated strips, etc.).
- Applicable standards or test requirements (e.g., salt spray, pull-out).
Frequently Asked Questions
What is the difference between 304 and 316 stainless steel wood screws?
304 (A2) offers good corrosion resistance for most outdoor and damp environments. 316 (A4) contains molybdenum, providing superior resistance to chlorides and saltwater, making it ideal for coastal and marine applications.
Can you produce custom sizes and head styles?
Yes, we are a custom stainless steel wood screws manufacturer. We can produce screws according to your drawings, including custom lengths, diameters, head styles, drive types, and thread forms.
Do your stainless steel wood screws require pre-drilling?
Our screws with sharp points and optimized thread designs can often be driven directly into softwoods and medium-hardwoods without pre-drilling. For hardwoods or dense materials, pre-drilling may be recommended to prevent splitting.
What quality certifications do you hold?
We are certified to ISO 9001 for quality management, ISO 14001 for environmental management, and ISO 45001 for occupational health and safety.
What is your typical lead time for bulk orders?
Lead times depend on the order size and customization level. We maintain a monthly capacity of 500 tons, and standard products can often be shipped within 2-3 weeks. Custom orders may require additional time for tooling and production.
