Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw is engineered to solve critical alignment and durability challenges in industrial settings. Its 6-32 UNC left-hand coarse threads with a Class 3A fit provide exceptional engagement for reverse-threading needs, preventing loosening in rotating assemblies. The standard shoulder with precise diameter and length control ensures accurate component positioning, reducing wear and misalignment in machinery, automation systems, and precision instruments. The knurled head and hex drive offer secure, tool-friendly installation, while the material's inherent corrosion resistance and high tensile strength make it suitable for demanding environments like aerospace, medical devices, and food processing equipment, where reliability and compliance are paramount.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a precision Class 3A thread fit. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005" for consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory acceptance.
