Secure Your Solar Investment with Anti-Corrosion Bi-Metal Screws
Our 6x25 Bi-Metal Screws are engineered specifically for the demanding environments of photovoltaic (PV) mounting systems. They combine a stainless steel head for corrosion resistance with a high-strength carbon steel thread, creating the perfect fastening solution where dissimilar metals meet. The proprietary RUSPERT coating provides an extra barrier, ensuring unparalleled protection against galvanic corrosion caused by weather and environmental exposure.
Key Features & Benefits:
Eliminates Galvanic Corrosion: The bi-metal construction and RUSPERT coating effectively prevent rust at critical connection points between aluminum rails and steel structures, extending system lifespan.
Engineered for Vibration Resistance: Withstands dynamic loads and constant thermal cycling, keeping your solar array secure over decades.
Optimized for Solar Applications: The precise 6x25mm size is ideal for securing mounting clips, L-feet, and other hardware to aluminum rails and steel purlins.
Maximum Durability: Offers the cost-effectiveness of carbon steel and the corrosion resistance of stainless steel in one superior product.
Technical Specifications:
Size: 6mm x 25mm
Material: Bi-Metal (Stainless Steel Head / Carbon Steel Body)
Coating: RUSPERT Anti-Corrosion Coating
Drive Type: Phillips or Star (T-25) available
Ideal for All Solar Applications:
Roof-Mounted PV Systems
Ground-Mounted Solar Farms
Carport and Balcony Solar Installations

Drill, Tap, and Fasten in One Step – The Ultimate Bi-Metal Solution
Speed up your construction and manufacturing projects with our Bi-Metal Self-Drilling Screws. These innovative fasteners feature a self-drilling point that cuts through steel, wood, and other materials without the need for a separate pilot hole. The bi-metal design delivers a high-strength thread while resisting corrosion, making them a versatile and reliable choice for a wide range of applications.
Key Features & Benefits:
Drill and Fasten Simultaneously: The integrated drill point saves significant time and labor costs by eliminating the pre-drilling step.
Dual-Material Performance: The carbon steel body provides superior clamping force, while the stainless steel head and RUSPERT coating resist rust at the exposed surface.
Exceptional Grip and Holding Power: Designed to create strong, durable connections in metal framing, steel sheets, and wood.
Versatile Application: Perfect for fastening wood to steel, sheet metal assemblies, and various structural framing tasks.
Technical Specifications:
Materials: Bi-Metal (Stainless Steel Head / Carbon Steel Body)
Coating: RUSPERT Anti-Corrosion Coating
Point Types: Available in various self-drilling point styles (e.g., TEK 2, TEK 3) for different material thicknesses.
Common Applications:
Metal Building and Framing
HVAC Installation
Roofing and Cladding
Wood-to-Steel Connections in Construction
