S-94302A115 M6 x 20 mm DIN 6921 Super-Corrosion-Resistant 316 Stainless Steel Serrated-Flange Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction for extended service life in harsh environments
• Enhanced load distribution from the integrated 14.2mm flange, reducing surface pressure and preventing loosening
• High tensile strength rated at 100,000 psi for reliable performance in demanding mechanical applications
• Secure fastening with Class 6g thread fit and serrated locking underside for vibration resistance
• Quick installation using standard external hex drive tools, compatible with common metric wrench sets
• Full thread engagement along the 20mm length for maximum grip strength in various material thicknesses
• Regulatory compliance with RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These M6 metric screws with flanged hex head design address critical engineering challenges in industrial assembly. The 316 stainless steel composition provides exceptional resistance to chemical and atmospheric corrosion, making these hex head screws ideal for marine, chemical processing, and food industry applications where moisture and corrosive agents are present. The integrated flange eliminates the need for separate washers while the external hex drive enables high-torque installation with common tools. The coarse thread pitch (1mm) ensures rapid assembly and reliable performance in softer materials or where vibration resistance is paramount. Manufactured to DIN 6921 specifications, these fully threaded fasteners deliver consistent quality and dimensional accuracy for precision engineering applications.

Specification Summary & Compliance

This M6 x 1mm flanged hex screw maintains Class 6g thread tolerance per ISO metric standards, ensuring precise fit and reliable performance. The fastener complies with DIN 6921 manufacturing specifications for dimensional accuracy and mechanical properties. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, confirming the absence of restricted substances. The combination of right-hand thread direction, coarse thread spacing, and fully threaded design provides optimal performance for general industrial fastening requirements.
