Professional Applications & Engineering Value
This 4-40 UNC shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, robotics, and precision equipment. The 18-8 Stainless Steel material offers exceptional corrosion resistance, reducing maintenance in humid or chemically aggressive settings. The 2" shoulder length with minimal tolerances ensures accurate positioning of moving parts, minimizing wear and misalignment. Combined with a 1/8" hex drive and knurled head, it allows for secure, tool-friendly installation in confined spaces. Partially threaded design and Class 2B UNC coarse threads facilitate faster assembly while maintaining strength, making it ideal for applications demanding reliability, such as conveyor systems, automotive fixtures, and electronic enclosures.
Specification Summary & Compliance
This shoulder screw features a 4-40 UNC thread with Class 2B fit for standard coarse threading applications, ensuring dimensional accuracy. Shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005" for precise engineering requirements. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets international environmental and safety standards for industrial components.
