S-95440A121 M8 x 16 mm ASTM A276 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for marine, chemical, and outdoor applications.
• Enhanced durability and wear resistance provided by the black oxide finish, which also adds a sleek, non-reflective appearance.
• Secure and efficient installation with the hex drive design, allowing for high torque application and reducing the risk of stripping.
• Reliable thread engagement and consistent performance with a Class 6g thread fit and coarse 1.25mm pitch, ensuring easy assembly and vibration resistance.
• High tensile strength of 70,000 psi and Rockwell B70 hardness for robust load-bearing capacity in demanding industrial settings.
• Optimized flush mounting with the undercut flat head profile, minimizing protrusion and providing a smooth surface finish.
• Full threading along the 16mm length for maximum grip and versatility in various material thicknesses.

Professional Applications & Engineering Value

These M8 flat head screws are engineered to address common industrial challenges such as corrosion, vibration loosening, and installation efficiency. The 316 stainless steel material offers exceptional resistance to chlorides and acidic conditions, making them suitable for marine equipment, chemical processing plants, and food machinery. The black oxide finish not only enhances corrosion protection but also reduces galling during high-torque applications. With a hex drive and coarse thread pitch, these screws enable quick, secure fastening in metals, plastics, and composites, reducing assembly time and maintenance needs. The undercut head design ensures a flush fit, preventing snagging and improving safety in automated systems. Ideal for OEM manufacturing, construction, and heavy-duty machinery, these screws deliver long-term reliability and compliance with industry standards.
