Professional Applications & Engineering Value
This hex headless set screw delivers exceptional engineering value in precision assembly applications where space constraints and vibration resistance are critical. The 18-8 stainless steel construction provides excellent corrosion resistance for automotive, aerospace, and marine environments, while the nylon patch thread locking technology eliminates the need for additional locking components, simplifying assembly processes. The Class 3A thread fit with UNC coarse spacing ensures consistent clamping force in machinery, electrical enclosures, and precision instruments. The cup tip design distributes pressure evenly, preventing damage to shaft surfaces while maintaining secure positioning of gears, pulleys, and collars in industrial equipment.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 specifications with Class 3A thread fit tolerance for precision assembly. Features UNC coarse thread spacing (6-32) with right-hand direction and Rockwell B80 hardness for durable performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The nylon patch thread locker maintains effectiveness across the specified temperature range of -50° to 250°F.
