Professional Applications & Engineering Value
This precision shoulder screw addresses critical alignment challenges in machinery assembly, where the precisely machined 10mm shoulder diameter with tight tolerances ensures accurate component positioning without additional bushings or spacers. The TiCN coated 18-8 stainless steel construction provides exceptional surface hardness and corrosion resistance, significantly reducing wear in high-cycle applications such as automated equipment, precision instruments, and rotating assemblies. The Class 6g thread fit and M8x1.25 coarse thread design enable quick assembly while maintaining vibration resistance, making these metric shoulder screws ideal for production environments requiring both precision and durability. The combination of Rockwell B55 hardness and 70,000 psi tensile strength ensures reliable performance under mechanical stress while the 5mm hex drive facilitates efficient installation in confined spaces.
Specification Summary & Compliance
This M8 shoulder screw features precision metric dimensions including Class 6g thread fit with M8x1.25 coarse threading, controlled shoulder diameter tolerance of -0.025 to 0mm, and shoulder length tolerance of 0 to 0.05mm. Manufactured from 18-8 stainless steel with TiCN coating and heat treated to Rockwell B55 hardness with 70,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
