2024.06.24 DD Fasteners: Premium Bi-Metal Self-Drilling Screws / Tapping Screws Unmatched Performance, Superior Durability

Key Features and Benefits:

Self-Drilling Efficiency: With a robust carbon steel drill point, these screws effortlessly penetrate hard metal surfaces up to 12mm thick, streamlining your projects by combining drilling, tapping, and fastening into a single operation.

Superior Corrosion Resistance: The A2/A4 stainless steel shank ensures long-lasting durability, even in the harshest environments. This means your installations will maintain their integrity and appearance over time, reducing maintenance needs.

Enhanced Safety and Performance: The drill points undergo induction heat treatment, which preserves the stainless steel shank's resistance to sensitization, thus enhancing the screw’s overall safety and reliability.

Cost-Effective Solution: By eliminating the need for separate drilling and tapping processes, these screws save valuable time and labor costs. Additionally, the reduced risk of corrosion translates to fewer repairs and replacements, offering significant cost savings over the product's lifecycle.

Protective Coatings: Available with Zinc, Ruspert, or other protective coatings, these screws provide additional layers of protection, ensuring the carbon steel point remains rust-free and extending the overall lifespan of the fastener.

Versatile Applications:

Our bi-metal self-drilling/tapping screws are ideal for a wide range of applications, including:

Construction and Roofing: Perfect for metal roofing and siding installations where strength and corrosion resistance are critical.
Automotive and Machinery: Suitable for assembling metal components where precision and durability are required.
HVAC and Electrical Systems: Ideal for securing metal parts in systems exposed to varying temperatures and environmental conditions.




The Best of Both Worlds:

By combining the strengths of two metals, DD Fasteners offers a screw that drills as efficiently as carbon steel and lasts as long as stainless steel. The zinc-plated carbon steel drill point provides excellent drilling performance while the stainless steel shank ensures outstanding corrosion resistance.
