S-91210A792 M3 x 8 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated alloy steel construction for extended service life in demanding environments
• Superior vibration resistance from the 90° cone point design that bites into materials, preventing loosening under dynamic loads
• Precise thread engagement with Class 5g6g tolerance ensuring reliable, consistent fastening in high-precision assemblies
• Optimized installation efficiency through the 1.5 mm hex drive and coarse 0.5 mm pitch, enabling quick seating with standard tools
• Exceptional mechanical strength from Rockwell C45 hardness, maintaining structural integrity under high clamping pressures
• Space-saving headless design allowing flush mounting in confined spaces where protruding fasteners aren't feasible
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial supply chain compatibility

Professional Applications & Engineering Value

This M3 set screw delivers critical engineering solutions through its specialized zinc-plated alloy steel construction and cone point geometry. The 90° cone point angle creates concentrated surface pressure that effectively resists rotational forces in pulley systems, gear assemblies, and shaft collars. The Class 5g6g thread fit provides precise dimensional control that eliminates play in precision machinery, while the coarse thread spacing enables rapid installation in production environments. The headless design with hex drive accommodates space-constrained applications where traditional fasteners would interfere with adjacent components. These combined features address common industrial challenges including component slippage, vibration-induced loosening, and corrosion in harsh operating conditions.
