Bimetallic composite self-drilling screws usually use an external hexagonal flange head, a main body of austenite SUS304/316, and a drill tail made of SCM435 alloy steel, which makes the screws have both excellent corrosion resistance and the strength of self-drilling screws. They are used in electronics, automobiles, steel structures, railways, machinery, aviation, docks, chemical plants, curtain walls, animal husbandry and other fields.

Bimetal Compound Self Drilling Screws - Reliable Fastening for Metal-to-Metal Applications
Product Features
- Bimetal Composition: Combines a hardened carbon steel drill point with a stainless steel body for both drilling efficiency and corrosion resistance.
- Self Drilling Capability: Eliminates the need for pre-drilling, ensuring precise and time-efficient installation on steel structures.
- Corrosion Resistance: Stainless steel body provides durability in harsh environments, reducing maintenance needs in outdoor or industrial settings.
Product Description
Bimetal compound self drilling screws are manufactured according to international mechanical fastening standards. Each screw is produced with strict dimensional tolerance control and undergoes quality testing to meet ISO and DIN specifications. The hardened drill point ensures penetration through thick steel sections, while the stainless steel body offers long-term performance against oxidation and corrosion. This combination makes them a practical solution for construction, industrial assembly, and HVAC system installations where both strength and environmental resistance are required.
Application Fields
This product is commonly used in:
- Steel-to-steel construction and assembly
- HVAC ducting and ventilation systems
- Metal roofing and cladding installation
- Industrial equipment and machinery fastening
FAQ
1. How do bimetal compound self drilling screws compare to standard stainless steel screws in heavy-duty applications?
Standard stainless steel screws may lack the hardness required for direct drilling into thick steel sections. Bimetal compound self drilling screws combine a hardened drill point with stainless steel corrosion resistance, making them more effective in structural steel connections where both penetration strength and durability are required.
2. Can these screws maintain performance in outdoor environments exposed to moisture and temperature fluctuations?
Yes. The stainless steel body of bimetal compound self drilling screws provides strong resistance to corrosion and oxidation. This makes them suitable for outdoor installations such as roofing, cladding, and HVAC systems where screws are exposed to moisture, condensation, and temperature changes.
3. What is the maximum steel thickness these screws can drill through without pre-drilling?
Depending on the screw size, bimetal compound self drilling screws can drill through steel thicknesses up to 6.0 mm. For thicker sections, pre-drilling may still be recommended to ensure proper fastening and maintain structural integrity.
