Professional Applications & Engineering Value

This precision shoulder screw solves critical alignment challenges in mechanical assemblies where rotational components must maintain exact positioning. The 25mm shoulder length with controlled tolerances serves as a precise locating dowel, eliminating the need for additional alignment components in industrial machinery, automation systems, and precision instruments. Manufactured from 18-8 stainless steel with a passivated finish, it resists corrosion in demanding environments while the hex socket drive allows for high-torque installation in space-constrained applications. The M3 metric thread with 0.5mm coarse pitch ensures rapid assembly while maintaining secure fastening, making it ideal for production lines requiring both precision and efficiency.
