- Optimized for automated assembly with smooth head texture and standardized socket profile for efficient production lines
Professional Applications & Engineering Value
This M6 shoulder screw delivers critical engineering value in precision mechanisms where alignment and durability are paramount. The 360 Brass material offers excellent corrosion resistance while maintaining electrical conductivity, making it ideal for electronic enclosures, marine components, and chemical processing equipment. The 12mm shoulder length with precise tolerances acts as a pivot or spacer, eliminating the need for additional bushings in rotating assemblies and linkages. The Class 6g thread with 1mm coarse pitch ensures rapid assembly and reliable performance in high-vibration environments like robotics, automotive systems, and industrial machinery. The hex socket head provides flush mounting where clearance is limited while allowing substantial torque transmission.
Specification Summary & Compliance
This precision shoulder screw features M6x1mm metric coarse thread with Class 6g tolerance per ISO standards. The shoulder maintains tight dimensional control with diameter tolerance of -0.025 to 0 mm and length tolerance of 0 to 0.05 mm. Manufactured from 360 Brass with Rockwell B55 hardness and 40,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations.
