Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and rotational needs in precision assemblies. Made from 316 stainless steel and finished with black oxide, it resists corrosion in demanding settings like marine, chemical processing, and outdoor machinery. The 16mm shoulder length and precise diameter tolerance provide a stable pivot or spacer, reducing wear on moving parts and ensuring accurate component positioning. The coarse M8x1.25 thread and hex drive facilitate quick, secure installation, while the knurled head enhances grip during handling. Ideal for applications in robotics, automotive systems, and industrial equipment, this fastener delivers long-term reliability and performance in high-stress environments.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit for consistent engagement, with a shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm to ensure precise fits. It conforms to ISO 7379 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmental and safety requirements in global supply chains.
