Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision assembly and machinery. The UNC coarse thread and Class 3A thread fit ensure quick, secure fastening with minimal risk of stripping, while the knurled socket head with hex drive allows for high-torque installation in confined spaces. The shoulder provides a stable bearing surface for rotating parts, reducing wear and maintaining alignment in industrial applications like robotics, conveyor systems, and electronic enclosures. Its corrosion-resistant properties make it suitable for marine, chemical processing, and food-grade environments, delivering reliable performance and reducing maintenance costs.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precise dimensional accuracy. The shoulder features tight tolerances (diameter: -0.004" to -0.002"; length: -0.005" to 0.005") to ensure consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for regulated industries and environmentally conscious operations.
