Professional Applications & Engineering Value
This 5/8"-11 UNC shoulder screw is engineered to address critical challenges in industrial machinery, automation, and assembly systems. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, while the black oxide finish adds an extra layer of protection against wear and galling. With a Rockwell B55 hardness and 70,000 psi tensile strength, it withstands high-stress conditions in applications like pivots, shafts, and rotating components. The 3/4" shoulder length ensures precise component spacing and alignment, reducing vibration and misalignment issues. Its coarse thread spacing and Class 2A thread fit facilitate quick assembly and disassembly, making it a reliable choice for maintenance-heavy environments. Ideal for use in automotive, aerospace, and heavy equipment sectors, this screw enhances operational efficiency and longevity.
Specification Summary & Compliance
This shoulder screw features a Class 2A thread fit with UNC coarse threads, ensuring dimensional accuracy and interchangeability. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005", providing precise manufacturing standards. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility for industrial use.
