Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction for extended service life in demanding environments
- Precise Class 3A thread fit ensures tight, secure fastening with minimal backlash in critical assemblies
- Vented design with 0.042" diameter allows pressure equalization and prevents fluid/air lock in sealed systems
- Hex drive (5/64") compatibility provides high torque transmission and prevents tool slippage during installation
- Cup point tip configuration creates deep indentation on shafts for maximum resistance to rotational forces
- Headless profile enables flush mounting in confined spaces where protruding fasteners are impractical
- Regulatory compliance with RoHS 3 and REACH standards ensures environmental responsibility and global market acceptance
Professional Applications & Engineering Value
Engineered for precision positioning and permanent component fixation, this 8-32 UNC set screw delivers exceptional performance in industrial machinery, automotive assemblies, and precision instruments. The 18-8 stainless steel composition provides inherent corrosion resistance that withstands exposure to moisture, chemicals, and temperature variations. The vented feature addresses common pressure differential issues in enclosed systems, while the cup point design bites securely into mating surfaces to prevent axial movement under vibration. With coarse UNC threads and Class 3A fit, this headless set screw maintains consistent clamping force in high-stress applications where reliability is paramount.
Specification Summary & Compliance
This 1/8" length set screw features 8-32 UNC coarse threads with Class 3A thread fit for precision tolerance. The right-hand thread direction and hex drive style (5/64") conform to industry-standard installation practices. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring hazardous substance restriction adherence for global industrial applications.
