• Easy installation and removal using a standard 5/64" hex key, saving time and reducing tool wear.
• Enhanced grip and alignment from the extended tip design, minimizing component slippage.
• Reliable coarse UNC threading for quick assembly and strong engagement in various materials.
• Compliance with industry standards including ASME B18.3, ensuring consistent quality and performance.

Professional Applications & Engineering Value

This 8-32 UNC set screw is engineered to address critical challenges in industrial assembly, such as securing rotating components against torque and vibration. The 18-8 Stainless Steel material offers excellent corrosion resistance, reducing maintenance in humid or chemical-exposed settings. Its headless design with a hex drive allows for flush mounting in tight spaces, while the extended tip improves contact and prevents loosening in high-stress applications like machinery, automotive systems, and precision instruments. The Class 3A thread fit and coarse thread spacing ensure rapid installation and reliable performance, making it a cost-effective solution for B2B procurement in demanding environments.

Specification Summary & Compliance

This set screw adheres to ASME B18.3 specifications, with precise dimensions including a 5/8" length, 8-32 UNC thread size, and Class 3A thread fit for tight tolerances. It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity. The extended tip features a diameter of 0.109" with controlled tolerances, supporting consistent performance in industrial applications.
