Professional Applications & Engineering Value
This precision shoulder screw is engineered to address critical alignment and durability challenges in industrial assemblies. The 18-8 Stainless Steel material, combined with a passivated finish, provides excellent resistance to corrosion and wear, making it ideal for machinery, automotive, and electronics where exposure to moisture or chemicals is common. The 7/8" shoulder length with precise tolerances ensures components like gears, pulleys, or bearings are accurately positioned, minimizing misalignment and reducing maintenance downtime. With a hex drive and UNC coarse threading, it enables quick, secure fastening in high-vibration environments, supporting efficient production and long-term operational stability.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. The shoulder features tight tolerances (diameter: -0.001" to 0", length: 0" to 0.002") to ensure precise fit in assemblies. Manufactured to high-quality specifications, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable usage across industries.
