S-97503A131 Length 13 mm DIN 7983, ISO 7051 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient thread cutting design creates precise mating threads in metal and sheet metal, reducing installation time and eliminating the need for pre-tapping.
• Secure and flush finishing provided by the oval head with an 80° countersink angle, ensuring a smooth surface and preventing snagging.
• Reliable drive engagement with the No. 2 Phillips drive, offering good torque transfer and reducing the risk of cam-out during installation.
• Full threading for maximum grip along the entire 13mm length, providing superior holding power in thin materials and sheet metal applications.
• Guaranteed dimensional precision and interchangeability, manufactured to comply with the stringent DIN 7983 and ISO 7051 standards.
• Safe for regulated industries as the screws are fully compliant with RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

This M3.9 metric tapping screw is engineered to solve common fastening challenges in metal and sheet metal assemblies. The 18-8 stainless steel material provides excellent resistance to oxidation and corrosion, which is critical for components exposed to moisture or varying temperatures. Its thread cutting (Type C) design allows it to form its own thread as it is driven, eliminating the need for a separate tapping operation and significantly speeding up production lines. The combination of a Phillips drive and a pointed tip ensures quick starts and efficient driving, reducing assembly time and labor costs. The oval head offers a finished appearance that sits flush with the material, making it ideal for applications where a smooth surface is required. These features make it a valuable, time-saving fastener for HVAC systems, electronic enclosures, automotive panels, and general metal fabrication.
