Professional Applications & Engineering Value
This 8-32 UNC set screw is engineered to address critical challenges in precision assemblies where space is limited and corrosion is a concern. The headless design and slotted drive enable installation in tight spaces, sitting flush with or below the component surface. Manufactured from 316 stainless steel, it offers excellent resistance to chemicals, saltwater, and industrial atmospheres, making it suitable for marine, chemical processing, and food-grade equipment. The cup point concentrates force on a small area, digging into the shaft material to prevent axial movement and resist loosening from vibration—a common failure point in machinery and rotating assemblies. Its coarse thread and Class 2A fit ensure quick assembly and reliable performance, providing a robust fastening solution for demanding applications.
Specification Summary & Compliance
This set screw features a 0.164" thread diameter and 3/16" length with a right-hand UNC coarse thread and Class 2A thread fit for standard dimensional accuracy and interchangeability. It is manufactured in accordance with ASME B18.3 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both performance reliability and environmental safety.
