Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating that protects against rust and extends service life in demanding environments
- Exceptional thread engagement with Class 3A fit ensuring precise, vibration-resistant fastening for critical assemblies
- High-strength durability from alloy steel construction with Rockwell C45 hardness that withstands heavy loads and repeated adjustments
- Secure, slip-resistant installation thanks to the 5/64" hex drive design that prevents tool cam-out under high torque
- Optimized for confined spaces with headless configuration and compact 3/16" length for applications where clearance is limited
- Reliable positioning performance with flat tip design that provides maximum surface contact and prevents component damage
- Industry-standard compatibility through UNC coarse threads that enable quick assembly and disassembly in common machinery
Professional Applications & Engineering Value
This 8-32 UNC set screw delivers critical engineering solutions where vibration resistance and space constraints challenge conventional fasteners. The black-oxide alloy steel construction provides superior corrosion protection in industrial environments while maintaining Rockwell C45 hardness for repeated adjustment cycles without thread deformation. The headless design with 5/64" hex drive enables installation in tightly spaced assemblies common in machinery, automotive components, and precision equipment. Class 3A thread fit ensures minimal backlash in high-vibration applications, while the flat tip distributes clamping force evenly to prevent surface marring on shafts, collars, and gears.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision tolerance. Features 8-32 UNC coarse threads with right-hand orientation and 0.164" thread diameter. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications.
