Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical challenges in precision assemblies, such as maintaining exact component spacing and resisting loosening under dynamic loads. The 316 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for applications in marine, chemical processing, and food-grade equipment. The hex socket head and knurled texture facilitate secure tool engagement and manual adjustments, reducing installation time and improving operator safety. With its coarse thread spacing and Class 5g6g thread fit, it ensures robust performance in high-vibration environments, while the precisely machined shoulder provides consistent alignment in rotating parts and bearing mounts, enhancing overall machinery reliability and lifespan.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 specifications, with a Class 5g6g thread fit ensuring dimensional accuracy and interchangeability. Key tolerances include a shoulder diameter of -0.072 to -0.01 mm and shoulder length of 0 to 0.25 mm for precise assembly. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in restricted substance-sensitive industries.
