S-94302A131 M8 x 40 mm DIN 6921 Super-Corrosion-Resistant 316 Stainless Steel Serrated-Flange Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction
• Enhanced load distribution and vibration resistance provided by the integrated 18mm flange
• High-strength fastening with a tensile strength of 100,000 psi for reliable performance in demanding applications
• Secure and efficient installation enabled by the external hex drive and coarse M8 x 1.25 mm thread
• Consistent and precise fit ensured by the Class 6g thread fit and DIN 6921 standard compliance
• Reduced risk of loosening due to the serrated locking underside of the flange
• Compliance with major environmental regulations including RoHS 3 and REACH for safe industrial use

Professional Applications & Engineering Value

This M8 flanged hex head screw is engineered to solve critical challenges in corrosive and high-stress environments. The 316 stainless steel material offers exceptional resistance to chemicals and saltwater, making it ideal for marine, chemical processing, and food industry applications. The integrated flange eliminates the need for a separate washer, providing a larger bearing surface that distributes clamp load effectively, prevents surface damage, and resists loosening under vibration—a common failure point in machinery and structural assemblies. The coarse metric thread and partial threading allow for faster installation and secure grip in a wide range of materials, from metal fabrications to heavy-duty equipment. This combination of corrosion resistance, structural integrity, and DIN 6921 compliance delivers long-term reliability and reduces maintenance cycles in professional engineering projects.
