  • High mechanical strength with 80,000 psi tensile strength and Rockwell B95 hardness for demanding applications
  • Reliable thread engagement through Class 6g thread fit and coarse 1mm pitch for secure fastening
  • Low-profile installation with smooth low socket head design requiring only 4mm hex drive
  • Environmental compliance meeting RoHS 3 and REACH regulations for global manufacturing standards
  • Right-hand coarse threading provides quick assembly and disassembly in industrial maintenance scenarios

Professional Applications & Engineering Value

These precision shoulder screws deliver exceptional value in applications requiring exact component positioning and rotational control. The 18-8 stainless steel construction with passivated finish addresses corrosion concerns in manufacturing environments, while the 8mm shoulder diameter with precise tolerance ensures accurate alignment in machinery, robotics, and automation systems. The low socket head profile with hex drive facilitates installation in confined spaces, and the Class 6g thread fit maintains consistent clamping force in vibrating equipment. Engineering teams specify these metric shoulder screws for their combination of 80,000 psi tensile strength and controlled shoulder dimensions, solving alignment challenges in precision assemblies while meeting international compliance standards.

Specification Summary & Compliance

This M6x1mm shoulder screw features Class 6g thread fit per metric standards with coarse thread spacing. The shoulder maintains precise dimensions with diameter tolerance of -0.025 to 0 mm and length tolerance of 0 to 0.05 mm. Manufactured from 18-8 stainless steel with passivated finish, the component demonstrates Rockwell B95 hardness and 80,000 psi tensile strength. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility in industrial applications.
