Professional Applications & Engineering Value
This shoulder screw is engineered to address common challenges in precision machinery, such as misalignment and component wear. The 18-8 stainless steel material, combined with a black oxide finish, provides excellent corrosion resistance, reducing maintenance in humid or chemical-exposed settings. The 3/4" shoulder length and precise diameter tolerances allow for accurate positioning of moving parts, minimizing friction in pivot points, linkages, and bearing assemblies. With a Class 3A thread fit and UNC coarse thread, it ensures tight, vibration-resistant connections in high-stress applications, from automotive to industrial equipment. The socket head with hex drive and knurled texture facilitates easy installation in confined spaces, enhancing assembly efficiency and reliability.
Specification Summary & Compliance
This shoulder screw features a Class 3A thread fit with 8-32 UNC coarse thread and a shoulder diameter tolerance of -0.004" to -0.002" for precise engineering applications. It meets ASME B18.3 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial reliability.
