• Robust thread engagement with a coarse M5x0.8 metric thread and Class 6g fit, providing strong holding power and resistance to vibration loosening.
• Enhanced durability and cleanliness from the passivated finish, which improves corrosion resistance and minimizes particle generation.
• Global compliance assurance by meeting RoHS 3 and REACH regulations, ensuring safety and environmental standards for international supply chains.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to corrosion and oxidation, making it suitable for machinery, automation systems, and outdoor equipment. The 10mm shoulder length with minimal tolerance ensures precise location and smooth rotation of assembled parts, reducing friction and wear. The hex socket drive and low-profile head allow for easy installation in tight spaces, while the M5x0.8 coarse thread ensures quick assembly and reliable fastening in high-vibration environments. This screw is ideal for pivots, guides, and spacers where precision alignment and long-term reliability are paramount.

Specification Summary & Compliance

This M5 shoulder screw features a metric thread with Class 6g tolerance for precise fit. The shoulder diameter is 6mm with a tolerance of -0.025 to 0 mm, and the shoulder length is 10mm with a tolerance of 0 to 0.05 mm, ensuring precise shoulder fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for industrial use.
