Professional Applications & Engineering Value
This 10-32 UNF shoulder screw is engineered to address critical alignment and durability challenges in industrial settings. Made from 18-8 stainless steel with a passivated finish, it resists corrosion in moist or chemical-exposed environments, extending service life. The 1-1/2" precise shoulder and smooth head ensure exact component positioning, reducing wear in machinery, pivots, and rotating assemblies. With a fine thread and Class 2A fit, it maintains tight tolerances in high-vibration applications like automotive, aerospace, and precision instruments. The hex drive design allows for efficient torque application, streamlining maintenance and reducing downtime in B2B operations.
Specification Summary & Compliance
This shoulder screw adheres to Class 2A thread fit and UNF thread standards, with precise shoulder diameter and length tolerances for consistent performance. It meets MS51576-25 (NASM51576) specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
