Professional Applications & Engineering Value
This 18-8 stainless steel shoulder screw is engineered to solve critical alignment and durability challenges in precision assemblies. The 6-32 UNC coarse thread and Class 3A thread fit ensure secure fastening in high-vibration environments like machinery, robotics, and automotive systems, preventing loosening under dynamic loads. The hex socket drive and knurled head provide superior torque transmission and handling, reducing installation errors. The precision-machined shoulder acts as a pivot, spacer, or bearing surface, eliminating the need for additional components and simplifying industrial assembly while maintaining exact positioning. Its corrosion-resistant properties make it suitable for applications exposed to moisture, chemicals, or outdoor conditions, ensuring long-term reliability and reduced maintenance.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.002" to 0.002", ensuring exact dimensional control. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of restricted hazardous substances and safe for industrial and commercial use.
