Professional Applications & Engineering Value
This 8-32 UNC Class 3A set screw delivers critical engineering solutions for industrial applications requiring permanent, vibration-resistant fastening. The Black-Oxide Alloy Steel construction provides excellent corrosion resistance while maintaining Rockwell C45 hardness for superior strength in high-stress environments. The integrated Nylon Patch thread locker eliminates the need for separate locking compounds, ensuring reliable performance in machinery, automotive assemblies, and precision equipment where vibration loosening poses significant operational risks. The coarse UNC thread with Class 3A fit guarantees precise engagement, while the cup point design creates permanent seating that prevents component slippage in power transmission systems and rotating assemblies.
Specification Summary & Compliance
This set screw features 8-32 UNC coarse threads with Class 3A fit for precision threading applications. Manufactured to ASME B18.3 standards, the fastener ensures dimensional accuracy and reliable performance. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety regulations for industrial use. The thread locker maintains performance across the specified temperature range of -50°F to 250°F, providing consistent locking capability in diverse operating conditions.
