- Enhanced corrosion resistance from Black-Oxide coating on alloy steel, extending service life in industrial environments
- High-strength durability with Rockwell C45 hardness, maintaining structural integrity under heavy loads and repeated use
- Precise torque application via 0.028" hex drive and headless design, ideal for confined spaces and flush mounting requirements
- Superior grip and alignment with cup point tip and fine UNF threads, preventing component slippage and ensuring accurate positioning
- Reliable performance standardization meeting ASME B18.3 specifications for consistent quality and interchangeability
- Environmental compliance assurance with RoHS 3 and REACH adherence, safe for regulated industries and global supply chains
Professional Applications & Engineering Value
This 0-80 UNF set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The headless hex drive design allows flush installation in precision machinery, jigs, and fixtures, while the cup point tip bites securely into shafts and collars to prevent rotational movement. Manufactured from Black-Oxide alloy steel with Rockwell C45 hardness, it withstands high-stress applications in automotive assemblies, aerospace components, and industrial equipment. The fine thread spacing and Class 3A thread fit ensure minimal backlash and reliable clamping force, addressing common failure points in dynamic load environments. Ideal for permanent fastening in robotics, conveyor systems, and precision instruments where tamper-resistant, low-profile fasteners are essential.
Specification Summary & Compliance
This set screw maintains Class 3A thread fit tolerance per UNF standards with 0-80 thread size and 5/16" length. Manufacturing conforms to ASME B18.3 specifications (ASTM F912) for dimensional accuracy and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring material safety and environmental responsibility.
