• High mechanical strength and durability from Rockwell B55 hardness and 40,000 psi tensile strength for reliable, long-term performance
• Secure, high-torque installation with the internal 2mm hex socket drive, preventing tool slippage and head stripping
• Accurate and consistent mating with Class 6g thread fit, ensuring reliable fastening in metric assemblies
• Streamlined regulatory compliance by meeting RoHS 3 and REACH standards, simplifying procurement for regulated industries
• Optimized for coarse threading applications with M3x0.5mm thread for faster assembly and reduced cross-threading risk

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment challenges in industrial applications such as machinery assemblies, precision instruments, and electronic enclosures. The 360 Brass material offers excellent corrosion resistance and non-magnetic properties, making it ideal for sensitive environments. The socket head with hex drive allows for high-torque installation in confined spaces, while the precisely toleranced shoulder diameter and 8mm shoulder length provide stable rotational control and accurate axial positioning of components. The M3x0.5mm coarse thread ensures quick assembly and reduces the risk of thread damage, delivering reliable performance in high-vibration settings where precise alignment is paramount.

Specification Summary & Compliance

This M3 shoulder screw features a Class 6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. The shoulder maintains a precise diameter tolerance of -0.025 to 0 mm and length tolerance of 0 to 0.05 mm for exacting assembly requirements. Manufacturing adheres to industry standards for socket head shoulder screws, with full compliance to RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial and electronic applications.
