Stainless Steel Pan Head Self Tapping Screws – Precision Fastening for Thin Metal Connections

When it comes to connecting thin metal plates—such as steel sheets, aluminum panels, or saw plates—stainless steel pan head self tapping screws provide a reliable, efficient, and durable fastening solution. These screws are engineered to cut their own threads into pre-drilled bottom holes, creating a strong, vibration-resistant hold without requiring separate tapping operations. Thanks to their high surface hardness (≥ HRC45), these screws can form threads directly within the material they’re driven into, making them ideal for metal-to-metal applications in construction, automotive, electrical systems, and industrial equipment assembly.

Robust Material Composition and Surface Treatments

The core material of these screws is carbon steel (C1022A), selected for its strength and ductility. To enhance corrosion resistance and surface durability, they are available with a variety of professional surface finishes, including: Zinc Plating, Nickel Plating, Phosphating and Chromium Plating. These coatings not only prolong the life of the screw but also offer options for aesthetic or application-specific needs. Available colors include blue, black, silver, and grey.

Design Details and Technical Specifications

The stainless steel pan head self tapping screw is engineered with precision and versatility in mind. Key specifications include:

· Type: Self Tapping Screw

· Standard: GB, DIN, BSW, ISO, ANSI

· Head Style: Round
