Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw with a Black Oxide finish is engineered to solve critical challenges in precision machinery, automation systems, and industrial equipment. The UNC coarse threads and Class 3A fit provide a tight, reliable fastening that resists loosening under vibration, essential for high-cycle applications. The knurled socket head and hex drive design facilitate secure tool engagement, preventing cam-out during installation. Its high tensile strength and corrosion resistance make it suitable for use in marine, chemical, and outdoor environments, reducing maintenance needs and downtime. The precisely machined shoulder ensures accurate alignment and spacing in assemblies like bearings, pulleys, and linkages, enhancing overall system reliability and performance.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A fit for precise thread engagement. Key dimensional tolerances include shoulder diameter (-0.004" to -0.002") and shoulder length (-0.005" to 0.005"), ensuring consistent performance. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for regulated industrial and commercial applications.
