Professional Applications & Engineering Value
Engineered for precision rotational and linear motion systems, this M5 shoulder screw solves critical alignment challenges in automated machinery and precision instruments. The 18-8 stainless steel construction provides exceptional corrosion resistance while maintaining Rockwell B55 hardness for wear resistance in high-cycle applications. The precise shoulder fit (-0.025 to 0 mm diameter tolerance) eliminates bushing requirements in conveyor systems, robotic arms, and optical equipment, reducing component count and assembly time. The Class 6g thread fit with 0.8mm coarse pitch ensures rapid installation while maintaining vibration resistance in automotive jigs and packaging machinery. The 14mm shoulder length provides optimal bearing surface for rotating components in medical devices and electronic enclosures.
