Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh environments
- Maximum holding power through the cup point tip design that bites into mating surfaces for secure, vibration-resistant fastening
- Precise thread engagement with Class 3A fit providing tighter tolerances for improved assembly consistency and load distribution
- Enhanced durability from Rockwell B80 hardness, offering excellent resistance to wear and deformation under stress
- Space-saving installation with headless hex drive design allowing flush mounting in confined spaces
- Quick installation using standard 1/16" hex tools with coarse UNC threads for faster driving and reduced cross-threading risk
- Regulatory compliance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial acceptance
Professional Applications & Engineering Value
This 6-32 UNC set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and corrosion protection are critical. The 18-8 Stainless Steel material provides inherent resistance to rust and chemical exposure, while the cup point tip creates permanent seating marks in shafts and collars to prevent rotational slippage. The headless hex drive design enables flush mounting in pulleys, gears, and couplings where protruding fasteners are impractical. With Class 3A thread fit and coarse UNC threads, these set screws maintain consistent clamping force in high-vibration environments like motor assemblies, machinery, and automotive components, solving common loosening issues in dynamic industrial applications.
Specification Summary & Compliance
This set screw features precision 6-32 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy. Manufacturing complies with ASME B18.3 specifications ensuring consistent quality and performance. The product meets RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) standards for chemical safety, making it suitable for global industrial markets requiring stringent environmental regulations.
