Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 1/2" shoulder length with precise fit tolerance acts as a reliable pivot or spacer, minimizing misalignment in machinery, robotics, and conveyor systems. Its UNC coarse threads and Class 2A thread fit ensure quick, secure fastening, while the passivated finish enhances corrosion resistance in humid or chemical-exposed environments. With a 70,000 psi tensile strength, it supports high-stress applications like motor mounts and fixture plates, reducing maintenance needs and downtime. The socket head design with hex drive allows for flush mounting in tight spaces, making it ideal for OEM equipment and automation systems where reliability and precision are paramount.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. The shoulder features precise tolerances: diameter of 7/32" (-0.001" to 0") and length of 1/2" (0" to 0.002"). Manufactured from 18-8 Stainless Steel with a passivated finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental and safety standards are upheld for industrial use.
