S-98070A922 M3 x 8 mm DIN 965 Sealing Stainless Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Superior Sealing Performance: Integrated Viton® fluoroelastomer O-ring ensures reliable, long-term sealing against fluids and gases, even under high-pressure conditions up to 6000 psi.
• Excellent Corrosion Resistance: Made from 18-8 stainless steel with a passivated finish, providing enhanced durability and resistance to rust in harsh industrial environments.
• Precise Thread Engagement: Class 6g thread fit and coarse M3 x 0.5mm pitch ensure easy installation and secure fastening, reducing the risk of cross-threading.
• Optimized Head Design: Undercut flat head with a 90° countersink angle allows for a flush, low-profile finish, ideal for applications where surface clearance is limited.
• Wide Temperature Tolerance: O-ring material withstands temperatures from -20° to 400° F, making it suitable for both extreme cold and high-heat applications.
• High Tensile Strength: With a tensile strength of 70,000 psi, this screw offers robust mechanical performance for demanding assembly requirements.
• Regulatory Compliance: Fully compliant with DIN 965 standards, RoHS 3, and REACH, ensuring safety and environmental responsibility in global supply chains.

Professional Applications & Engineering Value

This M3 flat head sealing screw is engineered to address critical challenges in industrial sealing applications where reliability under pressure and temperature fluctuations is paramount. The combination of 18-8 stainless steel and a passivated finish provides exceptional corrosion resistance, extending service life in moist or chemically aggressive environments. The integrated Viton® fluoroelastomer O-ring delivers consistent sealing performance, preventing leaks in hydraulic systems, pneumatic controls, and fluid handling equipment. Its undercut flat head design ensures a secure, flush fit, minimizing protrusion and improving aerodynamics or aesthetics in assembled products. With a maximum pressure rating of 6000 psi and broad temperature tolerance, it is ideal for use in automotive, aerospace, and manufacturing sectors where metric coarse threading and Phillips drive facilitate quick, tool-compatible installation.
