Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical challenges in precision assembly and machinery. Made from 316 stainless steel with a black oxide finish, it resists corrosion from chemicals, moisture, and high temperatures, extending service life in automotive, aerospace, and marine sectors. The 10mm shoulder diameter ensures accurate component positioning, preventing misalignment and reducing stress on connected parts. With a coarse thread and Class 5g6g fit, it offers quick installation and maintains integrity under vibration, while the hex socket drive and knurled head facilitate secure tightening in confined spaces. Ideal for pivots, guides, and rotating mechanisms, this screw delivers reliable performance where high tensile strength and environmental compliance are paramount.
Specification Summary & Compliance
This shoulder screw features precise dimensions, including a shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm, with threads conforming to Class 5g6g for metric coarse applications. It adheres to ISO 7379 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and quality in industrial use.
