- Enhanced durability and wear resistance from the black oxide finish, providing added protection against rust and abrasion.
- High tensile strength of 70,000 psi ensures reliable performance under heavy loads and mechanical stress.
- Precise Class 3A thread fit offers tight tolerances for secure, vibration-resistant assemblies in critical applications.
- Knurled socket head with hex drive allows for easy installation and removal, reducing tool slippage and improving grip.
- Coarse UNC threads facilitate quick assembly and disassembly, saving time in production and maintenance cycles.
- Compliance with ASME B18.3 standards guarantees consistent quality and interchangeability in engineering designs.
Professional Applications & Engineering Value
This shoulder screw is engineered to address common industrial challenges, such as misalignment and component wear in machinery. Made from 316 stainless steel with a black oxide finish, it resists corrosion from moisture, chemicals, and saltwater, making it suitable for marine, chemical processing, and outdoor equipment. The UNC coarse threads and Class 3A thread fit ensure precise engagement, reducing the risk of loosening under vibration in applications like robotics, conveyor systems, and automotive assemblies. The knurled socket head with a hex drive simplifies maintenance, while the high tensile strength supports heavy-duty use, enhancing reliability and reducing downtime in B2B operations.
Specification Summary & Compliance
This shoulder screw adheres to tight dimensional tolerances, including a Class 3A thread fit for high precision and UNC coarse threads with a size of 5/16"-18. It meets ASME B18.3 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for global industrial use.
