• Precision thread engagement with Class 6g tolerance provides consistent, vibration-resistant fastening in metric applications
• Optimized drive performance through JIS No. 2 drive design delivers secure tool engagement and reduced cam-out risk
• Enhanced load distribution from the pan head design minimizes surface damage while maintaining strong clamping force
• Maximum thread engagement with fully threaded design ensures superior holding power across the entire fastener length
• High tensile strength rated at 50,000 psi guarantees structural integrity under significant mechanical stress
• Industry-standard compliance with JIS B 1111 specifications ensures consistent quality and interchangeability

Professional Applications & Engineering Value

These M4 pan head screws deliver exceptional engineering value in precision assembly applications where corrosion resistance and thread reliability are critical. The 18-8 stainless steel composition provides excellent protection against oxidation and chemical degradation, making these fasteners ideal for electronics enclosures, industrial machinery, and marine equipment. The JIS drive system with No. 2 drive size ensures secure tool engagement that reduces stripping during high-torque installation. With Class 6g thread fit and coarse thread pitch (0.7mm), these screws offer rapid installation and vibration resistance in metric fastening applications, while the fully threaded design maximizes pull-out strength in demanding mechanical assemblies.
