Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. Its 3/8" shoulder diameter and 1-1/4" shoulder length with minimal tolerance deviations ensure exact positioning in industrial machinery and automation systems. The partially threaded design with 8-32 UNC coarse threads allows for secure fastening while minimizing thread wear. Combined with a knurled socket head for easy hex drive access, it reduces installation time and enhances torque efficiency. The high tensile strength and corrosion-resistant material make it ideal for applications requiring repeated adjustments and exposure to demanding conditions, providing long-term reliability and reduced maintenance.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2B thread fit for consistent engagement. The shoulder diameter tolerance is controlled between -0.004" to -0.002", and shoulder length tolerance is maintained at ±0.005" for precise assembly. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence in industrial applications.
