Professional Applications & Engineering Value
This precision shoulder screw delivers exceptional value in industrial automation, machinery assembly, and precision instrument manufacturing where component alignment is critical. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining Rockwell B55 hardness for durability in high-stress applications. The Class 6g thread with 0.6mm coarse pitch ensures rapid assembly without compromising joint integrity, while the precisely machined shoulder eliminates the need for additional spacers or bushings. The hex socket drive design allows for high-torque installation in confined spaces, making these metric shoulder screws ideal for robotics, conveyor systems, and precision mechanical assemblies requiring reliable, repeatable component positioning.
Specification Summary & Compliance
Manufactured to exacting standards with Class 6g thread fit per metric specifications, featuring precise shoulder dimensions (5mm diameter with -0.025 to 0 mm tolerance, 16mm length with 0 to 0.05 mm tolerance). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring strict material compliance.
