Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction for extended service life in harsh environments
- Maximum holding power achieved through Class 3A thread fit and fine UNF thread spacing for secure, vibration-resistant fastening
- Space-saving headless design with hex drive for flush mounting in confined spaces while maintaining easy installation
- Enhanced grip and minimal surface damage from the cup point tip that digs into shafts without excessive material displacement
- Consistent mechanical performance with Rockwell B80 hardness providing reliable strength and deformation resistance
- Broad industrial compatibility through compliance with ASME B18.3 specifications for dimensional accuracy and interchangeability
- Environmental regulation compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
Professional Applications & Engineering Value
These 0-80 UNF set screws deliver critical engineering solutions where space constraints and corrosion resistance are paramount. The 18-8 stainless steel construction prevents rust and chemical degradation in manufacturing equipment, precision instruments, and marine applications. The headless hex drive design allows complete flush mounting while the cup point creates permanent seating with minimal component damage. With fine thread spacing and Class 3A fit, these screws maintain position under high vibration, making them ideal for securing gears, pulleys, and collars in automotive, aerospace, and industrial machinery where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to ASME B18.3 standards with Class 3A thread fit for precision dimensional control. Features 0-80 UNF fine threads with right-hand direction, 5/32" length, and 0.028" hex drive. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Mechanical properties include Rockwell B80 hardness for consistent performance across industrial applications.
