S-95844A400 Length 13 mm DIN 7982 Type C Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Superior thread forming capability that creates strong, permanent threads in sheet metal without pre-drilling, reducing assembly time and labor costs.
• Optimized 80° countersink angle for a flush, professional finish that minimizes protrusion and improves safety in tight spaces.
• High drilling thickness capacity of up to 0.025", allowing secure fastening in thicker sheet metal applications with consistent performance.
• Full threading and pointed tip design for quick, self-starting installation and maximum grip across the entire screw length.
• Phillips drive with No. 2 size provides widespread tool compatibility and efficient torque transfer, reducing cam-out risks during high-speed assembly.
• Compliance with DIN 7982 Type C and RoHS 3 ensures consistent quality, material safety, and international acceptance for regulated industries.

Professional Applications & Engineering Value

These M3.9 metric tapping screws are precision-engineered for demanding sheet metal applications, where vibration resistance and material integrity are critical. The 18-8 stainless steel composition offers excellent corrosion resistance, making them ideal for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture. The thread forming technology eliminates the need for tapped holes, reducing installation steps and preventing metal chip accumulation in sensitive assemblies. With a fully threaded design and pointed tip, these screws ensure rapid penetration and uniform stress distribution, minimizing the risk of sheet metal distortion. The flat head with 80° countersink provides a smooth surface finish, essential for applications where aerodynamics or safety clearance is a concern. Trust these DIN 7982 Type C compliant fasteners to deliver reliable performance in automotive, aerospace, and industrial machinery sectors.
