Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and rotational requirements in precision machinery, automation systems, and assembly jigs. The 316 stainless steel material provides outstanding resistance to corrosive agents, making it suitable for marine, chemical processing, and food-grade equipment. The precisely ground shoulder diameter and length ensure accurate component positioning, reducing misalignment and wear in rotating assemblies. With its hex socket drive and coarse thread pitch, it enables rapid installation and disassembly while maintaining high clamp load. The passivated finish further enhances surface durability, making this shoulder bolt a reliable choice for high-cycle applications where precision and corrosion resistance are paramount.
Specification Summary & Compliance
This shoulder screw features an M8x1.25mm coarse thread with Class 6g thread fit per metric standards. Shoulder dimensions include a 10mm diameter (-0.025 to 0 mm tolerance) and 14mm length (0 to +0.05 mm tolerance) for precise fit. Manufactured from 316 stainless steel with a passivated finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring adherence to environmental and safety regulations for industrial fasteners.
