Professional Applications & Engineering Value

This precision shoulder screw addresses critical vibration-induced loosening challenges in industrial machinery and automated systems. The permanent nylon patch thread locker creates a chemical bond that withstands extreme temperature fluctuations from -70° to 250°F, eliminating the need for secondary locking mechanisms. The 18-8 stainless steel construction with passivated finish provides superior corrosion resistance in harsh environments, while the 30mm shoulder length with precise diameter control ensures accurate component spacing and alignment in metric assembly applications. The Class 6g thread fit guarantees consistent engagement in high-vibration scenarios, making it ideal for robotics, conveyor systems, and precision equipment where maintenance downtime must be minimized.

Specification Summary & Compliance

This M8 shoulder screw features Class 6g thread fit with 1.25mm coarse pitch, ensuring dimensional accuracy per metric standards. The shoulder maintains precise tolerances with diameter controlled at -0.025 to 0 mm and length at 0 to 0.05 mm. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental compliance for global industrial applications. The combination of 18-8 stainless steel material, passivated surface treatment, and nylon patch locking technology delivers reliable performance meeting international fastener standards.
