Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw is engineered to address critical challenges in precision assembly and high-stress environments. The UNC coarse thread and Class 3A fit provide excellent thread engagement and resistance to loosening under vibration, making it ideal for machinery, automotive, and aerospace components. The Black Oxide finish not only enhances corrosion resistance but also reduces galling, extending the fastener's lifespan in humid or chemically aggressive settings. With a knurled head and hex drive, it allows for efficient installation in confined spaces, while the precisely toleranced shoulder ensures accurate alignment of moving parts, minimizing wear and maintenance downtime in industrial applications.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Dimensions include an 8-32 thread size, 3/16" shoulder diameter, and 1/4" shoulder length, manufactured to tight tolerances (e.g., shoulder diameter tolerance of -0.004" to -0.002"). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances and suitable for global industrial use.
