Professional Applications & Engineering Value
This shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in precision machinery. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for applications in automotive, aerospace, and manufacturing equipment. The 5/16"-24 UNF fine thread and Class 2A fit ensure tight, reliable fastening that minimizes loosening under vibration, while the 1-3/4" shoulder length provides a stable pivot or spacer in assemblies like bearings and linkages. The hex drive and knurled head facilitate easy installation in confined spaces, reducing assembly time and improving operational efficiency in high-stress environments.
Specification Summary & Compliance
This shoulder screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent engagement and tight tolerances on the shoulder diameter and length. It conforms to UNF thread specifications and is manufactured from 18-8 stainless steel with a tensile strength of 70,000 psi. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial use worldwide.
