Stainless Steel Hex Flange Concrete Screw Anchor | Manufacturer
product detail
Description of Hex Flange Head Concrete Screw Anchor
Stainless Steel Hex Flange Head Concrete Screw Anchor is a self-tapping anchoring fastener designed specifically for concrete, masonry, and block substrates. The product features a hexagonal flange head with a one-piece molded flange, replacing the traditional combination of flat washers and spring washers, requiring no additional accessories during installation. The screw section uses a self-tapping thread design, allowing it to be directly screwed into pre-drilled holes or cut into the concrete substrate using a self-drilling method.
As a professional manufacturer and supplier of stainless steel hexagonal flange head concrete screws and concrete screw anchors, we offer a full range of specifications in 304 and 316 stainless steel, as well as OEM/ODM non-standard customization services. Direct from the source factory, our stainless steel hexagonal flange head concrete screws are priced transparently, and quality is fully controllable.
Advantages of Hex Flange Head Concrete Screw Anchor
Self-tapping threads, no pre-embedding required, highly efficient installation
The stainless steel hexagonal flange head concrete screws feature a self-tapping thread design, allowing direct screwing into pre-drilled holes. Installation requires no chemical anchors, no expansion tubes, and no waiting for curing—simply drill and install, significantly improving construction efficiency. Compared to traditional expansion anchors, installation time can be reduced by more than 50%.
Stainless steel material, corrosion resistant, suitable for harsh environments
Made with high-quality 304 or 316 stainless steel, offering excellent corrosion resistance and oxidation resistance. 316 stainless steel concrete screws contain molybdenum, providing even stronger resistance to chloride corrosion.
Standard compatibility, worry-free export
Products strictly adhere to domestic and international standards such as DIN 571, EN 14592, and GB/T 15856.4. As a professional supplier of stainless steel hexagonal flange head concrete screws, we support production according to multiple standards including Chinese national standards, German standards, and European standards to meet the needs of different export markets.
Factory direct supply, high cost performance
As a source factory and manufacturer of stainless steel hexagonal flange head concrete screws, we have complete production lines for cold heading, thread rolling, and heat treatment. Our direct supply model makes our stainless steel hexagonal flange head concrete screws more competitively priced, eliminating middlemen and ensuring full quality control.

Production Process
Application of Hex Flange Head Concrete Screw Anchor
Building Curtain Wall and Steel Structure Fixing
Stainless steel hexagonal flange head concrete screws are ideal anchors for building curtain walls and steel structures. They are used to connect curtain wall joists, steel beam supports, steel column bases, and concrete substrates. The hexagonal flange head provides reliable tightening and anti-loosening performance, while the stainless steel material ensures rust-free operation even after long-term outdoor exposure.
Pipe Support and Equipment Installation
Used for anchoring concrete foundations of pipe supports, cable trays, HVAC equipment, and fire protection systems. The self-tapping thread design makes installation convenient and efficient, significantly shortening the construction cycle. 316 stainless steel concrete screws are particularly suitable for humid and corrosive environments.
Fence and Safety Facility Fixing
Used for fixing concrete bases of road guardrails, bridge railings, stair handrails, and safety fences. High-strength anchoring capacity ensures the reliability of safety facilities under impact loads.
Renewable Energy and Outdoor Facilities
Suitable for concrete anchoring of solar photovoltaic brackets, wind turbine foundations, and communication base stations. Corrosion resistance and weather resistance make them perform excellently in long-term outdoor exposure environments.
Industrial Equipment and Heavy Machinery Foundations
Used for anchoring concrete foundations of compressors, generators, pump sets, and conveying equipment. High strength and reliable anchoring capabilities meet the stringent requirements for foundation fixation in industrial equipment.

FAQs
Q1: What are the installation steps for stainless steel hexagonal flange head concrete screws? What precautions should be taken?
A: Installation steps: ① Drilling – Use a carbide drill bit to drill a hole in the concrete substrate matching the screw diameter (refer to the installation instructions for hole diameter); ② Cleaning the hole – Use an air blower or brush to remove dust from the hole (incomplete cleaning will affect the anchoring force); ③ Screwing in – Use a power tool or socket wrench to screw in the screw, controlling the speed and torque. Precautions: Refer to the technical parameter table for installation torque to avoid excessive torque causing screw breakage or substrate cracking. For detailed installation guidance, please request the installation technical manual.
Q2: How to choose between 304 stainless steel and 316 stainless steel concrete screws?
A: 304 stainless steel (A2) contains 18% chromium and 8% nickel, has good corrosion resistance, and is suitable for general indoor environments, dry conditions, and general industrial scenarios, offering high cost-effectiveness. 316 stainless steel (A4) contains 2%-3% molybdenum compared to 304, resulting in significantly better resistance to chloride corrosion. It is particularly suitable for highly corrosive environments such as marine settings, chemical equipment, high-salt-spray areas, and long-term outdoor exposure. Selection recommendation: 304 is generally sufficient for general construction projects; 316 is recommended for coastal areas, chemical plants, and wastewater treatment plants. Welcome to consult our stainless steel hexagonal flange head concrete screw manufacturer for professional selection advice.
Q3: Do you support non-standard customization of stainless steel hexagonal flange head concrete screws? What are the minimum order quantity and delivery time?
A: Yes. As a professional manufacturer of stainless steel hexagonal flange head concrete screws, we provide complete non-standard customization and OEM/ODM services. Standard products and commonly used specifications are always in stock and can be shipped on the same day; non-standard customization usually takes 3-7 days for sampling, with the specific delivery time depending on the complexity of the process and the order quantity. Flexible minimum order quantities are available, supporting both small-batch trial production and large-volume purchases. We welcome you to provide drawings or samples to discuss your needs.
