A 4.2 mm self-drilling screw that cuts a clean hole through a 2 mm steel bracket will spin in place on a 0.8 mm cladding panel, and the same screw that holds a dry indoor ceiling together can rust to the surface within a season on a coastal roof. Neither failure is a manufacturi...

READ MOREAnhui Linghong Hardware Technology Co., Ltd. is a specialized Stainless Steel/Stainless Iron Drywall Screws manufacturer and supplier, producing corrosion-resistant fasteners for gypsum board, fiberboard, and light steel stud applications. Our range covers both 304 austenitic and 410 martensitic stainless grades, with options for bugle or pan heads, coarse or fine threads, and partial or full thread configurations.
With over 20 years in the fastener industry and a 12,600 m² factory in Anhui, China, we combine mature production systems with ISO 9001, ISO 14001, and ISO 45001 certified processes. Our monthly output of approximately 500 tons supports both standard catalog items and custom-engineered solutions for global construction and interior decoration projects.
The choice between 304 and 410 stainless steel directly affects corrosion resistance, magnetic properties, and cost. We produce both grades and help you match the material to the environmental exposure and mechanical demands of your project.
| Grade | Key Properties | Typical Applications |
|---|---|---|
| 304 (A2) | Excellent corrosion resistance, non-magnetic, good formability | Humid or coastal environments, outdoor cladding, areas requiring long-term rust prevention |
| 410 | Magnetic, high hardness after heat treatment, cost-effective | Indoor ceilings, partitions, drywall-to-steel stud fastening |
Our stainless drywall screws are available in several head styles and thread patterns to suit different installation methods and substrates. We manufacture both self-tapping screws for steel studs and thread-forming screws for wood framing.
We also offer custom lengths, diameters, and head markings. For example, we produce 4.8×90–120 mm bugle head screws with 4 ribs for enhanced countersinking, as well as high-tail designs for collated or strip-fed systems.
As a full-process factory, we control every step from wire drawing to heat treatment and surface finishing. Our production lines are equipped with over 80 sets of machinery, including cold heading, thread rolling, and automated inspection systems. This vertical integration ensures consistent quality and traceability for large-volume orders.
We apply strict process controls, including first-piece inspection, in-process patrol checks, and final ex-factory testing. Our quality lab uses metallographic polishing machines and Rockwell hardness testers to verify case depth and core hardness, ensuring that screws resist stripping and breakage during power driving.
Our quality management system is certified to ISO 9001, and we also maintain ISO 14001 (environmental) and ISO 45001 (occupational health and safety) certifications. These certifications reflect our commitment to consistent product quality and responsible manufacturing practices.
For each batch, we document material certificates, heat treatment records, and dimensional inspection results. We can provide these reports with your shipment to support your own incoming quality control.
We understand that efficient packaging and reliable delivery are critical for construction projects. Our packaging options include:
We export 40–50 containers to Australia and about 10 containers to Europe and Japan monthly, demonstrating our experience in international shipping and documentation.
To prepare an accurate quotation and production plan, please provide the following details:
With this information, we can recommend the optimal screw design and provide samples for your testing before mass production.
Stainless iron typically refers to martensitic grades like 410, which are magnetic and can be hardened. Stainless steel often refers to austenitic grades like 304, which are non-magnetic and offer higher corrosion resistance. We produce both, so you can choose based on your application's exposure and mechanical needs.
Yes, we offer custom sizes within our production capabilities. Common diameters range from 3.5 mm to 4.8 mm, and lengths from 25 mm to 120 mm. For special requirements, please contact us with your specifications.
Yes, we can provide samples for pre-production validation. Please share your application details so we can recommend the most suitable screw type and send samples accordingly.
Lead time depends on the order quantity and customization level. For standard items, we typically ship within 2–3 weeks after order confirmation. Custom products may require additional time for tooling and production.
We control the heat treatment process to achieve optimal hardness and case depth. Our screws are tested for torsional strength and hardness to meet industry standards, reducing the risk of failure during power driving.
Our portfolio also includes Products, Wood Screw, Carbon Steel Wood Screws for applications with different operating ranges, interfaces or integration requirements.
