Professional Applications & Engineering Value
This precision shoulder screw solves critical alignment challenges in industrial machinery, automation systems, and precision instruments. The 18-8 stainless steel construction combined with TiCN coating provides exceptional surface hardness and corrosion resistance, significantly reducing wear in dynamic applications. The Class 6g thread fit ensures consistent engagement in metric threaded assemblies, while the precisely machined shoulder with controlled diameter tolerance enables accurate component positioning and rotational stability. The coarse thread pitch (M4x0.7mm) facilitates quicker assembly in production environments, and the Rockwell B55 hardness maintains dimensional stability under operational stresses. These features make it ideal for precision mechanisms requiring repeatable alignment and durability.
Specification Summary & Compliance
Manufactured to exacting standards with Class 6g thread tolerance per metric threading specifications. Shoulder diameter maintains tight tolerance of -0.025 to 0 mm with shoulder length tolerance of 0 to 0.05 mm for precision fit applications. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use worldwide.
