S-90505A447 M3 x 14 mm DIN 965 Sealing Stainless Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh chemical and marine environments.
• Reliable pressure sealing up to 6000 psi, preventing leaks in critical fluid and gas handling systems.
• Wide temperature compatibility from -40° to 225° F (-40° to 107° C) thanks to the integrated Buna-N rubber O-ring.
• High mechanical strength with a 70,000 psi tensile strength, ensuring fastener integrity under heavy loads.
• Precise and secure fastening with a Class 6g thread fit and coarse M3x0.5mm pitch for quick assembly and vibration resistance.
• Flush, low-profile installation with an undercut flat head design (DIN 965), perfect for applications where a smooth surface is required.
• Streamlined procurement and compliance, meeting DIN 965 standards and global RoHS 3 & REACH environmental regulations.

Professional Applications & Engineering Value

This M3 flat head screw is engineered to solve critical sealing and corrosion challenges in demanding industrial applications. The combination of 316 stainless steel and a Buna-N rubber O-ring creates a robust seal against high-pressure fluids, gases, and environmental contaminants, making it indispensable for pumps, valves, compressors, and fluid power systems. The undercut flat head profile ensures a flush fit, eliminating protrusions that could interfere with machinery operation. Its coarse metric thread and Phillips drive facilitate rapid installation and maintenance, reducing assembly time while the material's inherent resistance to chlorides and acids extends service life, minimizing downtime and replacement costs in aggressive operational environments.
