S-91217A303 M8 x 8 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Maximum holding power achieved through Class 6g thread fit and 120° cone point design that bites deeply into mating materials
• Easy installation and removal with 4mm hex drive that provides excellent torque transmission without stripping
• Reliable thread engagement with coarse 1.25mm pitch threads that resist loosening under vibration and dynamic loads
• Space-saving headless design allows for flush mounting in applications where clearance is limited
• Consistent mechanical properties with Rockwell B80 hardness ensuring durability and repeated use capability
• Global compliance assurance meeting RoHS 3 and REACH environmental regulations for international projects

Professional Applications & Engineering Value

These M8 x 1.25mm DIN 914 set screws deliver exceptional engineering value in precision assembly applications where vibration resistance and secure positioning are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery operating in humid or chemically aggressive environments, while the 120° cone point creates positive locking action that prevents component slippage in power transmission systems, gear assemblies, and rotating machinery. The headless design with 4mm hex drive enables flush mounting in confined spaces while maintaining high torque capability. Manufactured to DIN 914/ISO 4027 standards, these metric set screws ensure dimensional consistency and reliable performance in automotive, manufacturing, and industrial equipment applications where precision alignment and secure fastening are paramount.

Specification Summary & Compliance

This M8 set screw features Class 6g thread fit tolerance per metric standards with 1.25mm coarse thread pitch spacing. Manufactured to DIN 914 specifications (equivalent to ISO 4027) with 120° cone point angle and 8mm length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global industrial applications and restricted substance requirements.
