Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address critical alignment and spacing challenges in precision assemblies. The 18-8 stainless steel material provides superior corrosion resistance, making it suitable for applications in electronics, machinery, and automotive sectors where exposure to moisture or chemicals is a concern. The 4mm thread length and 8mm shoulder work together to securely fasten components while maintaining exact positioning, reducing the risk of misalignment. With a coarse thread pitch and right-hand thread direction, it ensures quick installation and reliable performance in high-vibration environments. The socket head design allows for compact assembly, ideal for space-constrained applications requiring robust fastening solutions.
Specification Summary & Compliance
This precision shoulder screw features a Class 6g thread fit per metric standards, ensuring dimensional accuracy for consistent performance. The shoulder diameter tolerance is -0.025 to 0 mm, and shoulder length tolerance is 0 to 0.05 mm, providing precise fit for engineering applications. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use.
