Professional Applications & Engineering Value
This 10-24 UNC set screw delivers exceptional engineering value in applications requiring permanent, vibration-resistant fastening. The 18-8 stainless steel construction provides superior corrosion resistance for harsh industrial environments, while the nylon patch thread locker effectively prevents loosening in machinery, automotive components, and precision equipment. The Class 3A thread fit ensures precise engagement with mating components, reducing the risk of cross-threading and ensuring consistent clamping force. The hex headless design allows for flush mounting in space-constrained assemblies, making it ideal for shaft collars, gears, and pulleys where reliable positioning is critical. With its coarse thread spacing and cup tip, this fastener provides excellent holding power while minimizing damage to shaft surfaces.
Specification Summary & Compliance
This set screw features 10-24 UNC threads with Class 3A thread fit for precision engagement and meets ASME B18.3 manufacturing specifications. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications. The combination of precise dimensional control and certified compliance makes this set screw suitable for quality-conscious manufacturing environments requiring reliable, regulation-compliant fastening solutions.
