Professional Applications & Engineering Value

Engineered for precision mechanical assemblies, these M3 shoulder screws provide critical alignment and secure fastening in industrial equipment, automation systems, and precision instruments. The 18-8 stainless steel construction with passivated finish ensures corrosion resistance in challenging environments, while the nylon patch locking technology prevents loosening under vibration—a common failure point in rotating machinery and moving assemblies. The precisely machined shoulder diameter (4mm with tight tolerance) and 6mm shoulder length enable accurate component positioning and rotational control, eliminating the need for additional spacers or alignment fixtures. These metric shoulder screws with coarse thread pitch offer quick assembly while maintaining the strength required for high-stress applications across manufacturing, robotics, and electronic enclosures.

Specification Summary & Compliance

This precision shoulder screw features M3x0.5mm coarse threads with Class 6g thread fit tolerance, ensuring consistent engagement in metric assemblies. The shoulder maintains precise dimensions with diameter tolerance of -0.025 to 0 mm and length tolerance of 0 to 0.05 mm for accurate component alignment. Manufactured to industrial standards using 18-8 stainless steel with passivated surface treatment, these fasteners are RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international regulatory requirements for hazardous substances.
