Key Features & Benefits at a Glance
- Maximum holding power with Class 3A thread fit ensuring precise, vibration-resistant connections in demanding applications
- Superior corrosion resistance from black oxide coating on alloy steel, extending service life in harsh industrial environments
- Enhanced torque transmission through 5/16" hex drive design, preventing tool slippage and enabling high-tightening precision
- Deep penetration capability with extended tip design (0.328" length) for secure seating in shaft collars and pulleys
- Exceptional durability from Rockwell C45 hardness, maintaining thread integrity under repeated adjustments and heavy loads
- Reliable coarse threading (5/8"-11 UNC) for quick assembly and reduced cross-threading risks in maintenance operations
- Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global supply chain integration
Professional Applications & Engineering Value
Engineered for precision shaft locking and component positioning, this headless set screw solves critical alignment challenges in power transmission systems and rotating assemblies. The black oxide alloy steel construction provides superior corrosion protection while maintaining Rockwell C45 hardness for wear resistance in high-vibration environments. The extended tip design ensures deeper penetration into mating surfaces, preventing slippage in conveyor systems, gear assemblies, and motor couplings. With 5/8"-11 UNC coarse threads and Class 3A fit, it delivers reliable performance in agricultural machinery, industrial automation, and heavy equipment where right-hand threading and 5/16" hex drive facilitate efficient maintenance and assembly operations.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision tolerance. Features 5/8"-11 UNC coarse thread spacing with 0.625" thread diameter and extended tip dimensions (0.328" length, 0.468" diameter). Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage in international industrial markets.
