Professional Applications & Engineering Value
This precision shoulder screw addresses critical alignment challenges in industrial machinery, automation systems, and precision instruments. The 316 stainless steel material combined with passivated finish provides exceptional resistance to chemicals, moisture, and industrial atmospheres, significantly reducing maintenance frequency in corrosive environments. The precisely controlled 8mm shoulder diameter with tight tolerance serves as a reliable locating feature for rotating components, bearings, and linkages, eliminating the need for additional alignment components. The Class 6g thread fit and coarse thread pitch ensure rapid assembly while maintaining secure fastening integrity, making these metric shoulder screws ideal for high-volume manufacturing applications requiring both precision and efficiency.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 6g thread tolerance per metric thread specifications. Shoulder diameter maintains tight tolerance of -0.025 to 0mm with shoulder length tolerance of 0 to 0.05mm for precise fitment. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance control.
