S-91210A818 M6 x 8 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated alloy steel construction, ensuring long-term reliability in demanding industrial environments
• Superior holding power from the 90° cone point design that bites securely into mating materials, preventing component slippage
• Consistent torque transmission via the 3mm hex drive, allowing for precise installation with standard tools
• Reliable thread engagement with Class 5g6g tolerance coarse threads, providing vibration-resistant fastening in high-stress applications
• Exceptional mechanical strength from Rockwell C45 hardness, maintaining dimensional stability under heavy loads
• Space-saving headless design ideal for applications where flush mounting is required without protruding components
• Global compliance assurance meeting RoHS 3 and REACH environmental standards for international supply chain compatibility

Professional Applications & Engineering Value

This M6 set screw delivers critical engineering solutions for precision assembly applications where component positioning and security are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, automotive components, and electrical enclosures exposed to harsh operating conditions. The cone point configuration creates permanent registration marks in shafts and collars, preventing relative movement in power transmission systems. With its headless hex drive design, this metric set screw installs flush with surfaces, making it ideal for confined spaces in manufacturing equipment, robotics, and precision instruments. The coarse thread profile ensures rapid installation while maintaining the Class 5g6g tolerance specified in DIN 914/ISO 4027 standards for consistent performance across production runs.

Specification Summary & Compliance

This precision fastener maintains Class 5g6g thread fit tolerance per ISO metric standards, ensuring consistent engagement across mating components. Manufacturing complies with DIN 914 ISO 4027 specifications for dimensional accuracy and mechanical properties. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, confirming restriction of hazardous substances for global industrial applications.
