Key Features & Benefits at a Glance
- Superior vibration resistance with nylon patch thread locker that maintains locking performance up to 250°F
- Precise thread engagement through Class 3A external thread fit ensuring reliable fastening in demanding applications
- Enhanced gripping power with extended tip design that increases surface contact and prevents component slippage
- High-strength durability from alloy steel construction with Rockwell C45 hardness for long-term performance
- Easy installation and removal using standard 5/64" hex drive tooling while maintaining headless profile
- Broad industrial compatibility with UNC coarse threads and right-hand direction meeting common assembly requirements
- Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards including RoHS 3 and REACH
Professional Applications & Engineering Value
These 8-32 UNC set screws deliver critical vibration-resistant performance in industrial machinery, automotive components, and precision equipment where secure fastening is paramount. The alloy steel construction provides exceptional shear strength while the nylon patch locking mechanism effectively counters loosening from continuous operational vibrations. The extended tip design creates deeper penetration into mating components, distributing clamping force more effectively than standard set screws. This combination of Class 3A thread fit precision and temperature-resistant locking makes these fasteners ideal for permanent assemblies in harsh environments where maintenance access is limited and reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A external thread fit tolerance for precision engagement. Features UNC coarse threads (8-32) with right-hand direction and meets Rockwell C45 hardness standards. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The extended tip maintains dimensional accuracy with tip diameter of 0.109" (-0.006" to 0 tolerance) and tip length of 0.043" (-0.006" to 0 tolerance) for consistent performance across production batches.
