Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
- Precise thread engagement with Class 3A fit ensuring reliable, vibration-resistant fastening in critical applications
- Enhanced torque transmission through 5/64" hex drive design for secure installation without head protrusion
- Maximum grip strength from cup point tip that creates permanent seating in shafts and collars
- Optimized mechanical properties with Rockwell B80 hardness balancing durability and machinability
- Industry-standard compatibility with UNC coarse threads (8-32) for easy replacement and interchangeability
- Environmental compliance assurance meeting RoHS 3 and REACH regulations for global supply chain integration
Professional Applications & Engineering Value
This 8-32 UNC set screw delivers exceptional engineering value in precision assembly applications where space constraints and vibration resistance are critical. The headless design with hex drive allows flush mounting in confined spaces while maintaining high torque capability. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance for industrial equipment, automotive components, and machinery exposed to moisture or chemicals. The cup point tip creates deep indentation in mating surfaces, preventing rotational slippage in pulley systems, gear assemblies, and coupling applications. With coarse thread spacing and Class 3A thread fit, it ensures rapid installation and reliable performance in high-vibration environments where fine adjustments aren't practical.
Specification Summary & Compliance
This 1-1/4" length set screw features precision 8-32 UNC threads with Class 3A thread fit for tight tolerance applications. The fastener complies with ASME B18.3 dimensional standards and maintains Rockwell B80 hardness for consistent mechanical performance. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, ensuring environmental responsibility in industrial supply chains.
