S-90505A366 M2 x 4 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 high-pressure sealing up to 6000 psi, preventing leaks in critical fluid and gas systems.
• Wide temperature tolerance from -80° to 400° F (-62° to 204° C) thanks to the integrated silicone rubber O-ring.
• Exceptional mechanical strength with a 70,000 psi tensile strength, ensuring durability under heavy loads.
• Precision thread fit (Class 6g) for smooth installation and secure fastening in metric assemblies.
• Undercut flat head design allows for a flush, low-profile finish that minimizes protrusion.
• Compliance with DIN 965 and environmental standards (RoHS 3, REACH) for guaranteed quality and safety.

Professional Applications & Engineering Value

These M2 metric sealing screws are engineered to solve critical challenges in industrial applications where pressure integrity and corrosion resistance are paramount. The combination of 316 Stainless Steel and a silicone rubber O-ring ensures long-term performance in aggressive environments, from chemical processing equipment to marine hardware. The fully threaded design with a coarse 0.4 mm pitch and Phillips drive facilitates quick, reliable installation, while the flat undercut head sits flush to prevent snagging. Ideal for sealing in pumps, valves, and electronic enclosures, these screws help eliminate fluid leaks and reduce maintenance downtime.
