- Precise component alignment and secure positioning ensured by the smooth, precisely machined shoulder with controlled diameter and length tolerances.
- High tensile strength (70,000 psi) and hardness (Rockwell B55) for reliable performance under significant mechanical loads.
- Easy installation and removal in confined spaces with the hex socket drive and 3 mm drive size.
- Accurate and reliable threading with Class 6g thread fit and coarse M5x0.8 metric thread for quick assembly.
- Compliance with strict environmental regulations including RoHS 3 and REACH, ensuring safe and sustainable use.
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and wear challenges in industrial applications. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, while the TiCN coating significantly enhances surface hardness, reducing galling and wear in high-friction environments like rotating machinery, automotive assemblies, and precision instruments. The precise shoulder fit with tight diameter and length tolerances ensures accurate location of parts, preventing misalignment and reducing stress concentrations. With a hex socket head and coarse metric thread, it allows for efficient installation in tight spaces, making it a reliable mechanical fastener for demanding engineering projects that require durability, precision, and regulatory compliance.
Specification Summary & Compliance
This shoulder screw features a Class 6g thread fit for standard metric threading, with a shoulder diameter tolerance of -0.025 to 0 mm and shoulder length tolerance of 0 to 0.05 mm to ensure precise assembly. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its compliance for industrial use without hazardous substances.
