S-91280A272 M16 x 60 mm ISO 4017, DIN 933 Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 110,000 psi tensile strength for reliable performance in high-stress applications
• Superior corrosion resistance thanks to black steel construction and full compliance with RoHS 3 and REACH environmental standards
• Optimal thread engagement with Class 6g thread fit and coarse 2mm pitch for faster installation and reduced cross-threading risk
• Enhanced durability from Rockwell C21 hardness rating that maintains fastener integrity under repeated stress
• Maximum driving torque capability through external hex drive design with 24mm head width for secure tool engagement
• Full-length thread coverage ensures consistent clamping force distribution along the entire 60mm length
• Global compatibility with ISO 4017 certification (equivalent to DIN 933) for standardized metric fastener applications

Professional Applications & Engineering Value

These M16 hex head screws deliver critical engineering solutions where high tensile strength and reliable fastening are paramount. Manufactured from Class 8.8 steel with Rockwell C21 hardness, they withstand vibration, shock loads, and environmental stressors in heavy machinery, structural steel connections, and industrial equipment assembly. The metric coarse thread with 2mm pitch provides rapid installation in steel-to-steel applications while maintaining excellent shear resistance. The fully threaded design ensures uniform stress distribution across the entire 60mm length, preventing joint failure in dynamic loading conditions. With ISO 4017 certification and external hex drive compatibility, these fasteners integrate seamlessly into global manufacturing standards while offering superior torque transmission for maintenance-critical applications.

Specification Summary & Compliance

This M16 x 2mm hex head screw features Class 6g thread fit tolerance per metric standards with right-hand thread direction. Manufacturing complies with ISO 4017 specifications (equivalent to DIN 933) for dimensional accuracy and mechanical properties. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for hazardous substance restrictions. With 60mm fully threaded length, 24mm hex head width, and 10.2mm head height, these components deliver precise dimensional consistency for industrial applications requiring standardized metric fasteners.
