Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and assembly jigs. Its UNC coarse thread and Class 3A fit provide superior resistance to loosening under vibration, a common issue in dynamic industrial environments. The knurled socket head with a hex drive ensures reliable torque transmission, reducing installation errors and maintenance downtime. Made from corrosion-resistant 316 stainless steel, it excels in applications exposed to moisture, chemicals, or extreme temperatures, such as marine equipment, food processing machinery, and chemical handling systems. The precise shoulder diameter and length facilitate accurate component positioning, making it ideal for pivots, spacers, and rotating assemblies where alignment is crucial for operational efficiency and longevity.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precise tolerance. Key dimensional specifications include a shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005". It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
