Key Features & Benefits at a Glance
- Enhanced Corrosion Resistance: Black-oxide coating on alloy steel provides reliable protection against rust in demanding industrial environments, extending service life.
- Superior Thread Precision: Class 3A thread fit ensures tight, secure fastening with minimal backlash, ideal for high-vibration applications.
- High Strength and Durability: Rockwell C45 hardness offers excellent wear resistance and maintains integrity under heavy loads.
- Space-Saving Headless Design: Flush installation allows for compact assemblies where protruding fastener heads are not feasible.
- Efficient Installation and Removal: 1/16" hex drive enables quick, tool-accessible tightening in confined spaces.
- Wide Compatibility: UNC coarse threads facilitate easy engagement and are standard in many North American industrial components.
- Regulatory Compliance Assurance: Meets ASME B18.3, RoHS 3, and REACH standards, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This 6-32 UNC set screw is engineered to address critical challenges in precision assemblies, such as shaft collars, gears, and pulleys, where vibration resistance and reliable positioning are paramount. The black-oxide alloy steel construction combats corrosion in harsh conditions, while the Class 3A thread fit minimizes loosening under dynamic loads. Its headless hex drive and flat tip design ensure a flush finish, preventing interference in compact machinery. By integrating coarse thread spacing and right-hand threading, it simplifies installation in automotive, aerospace, and manufacturing equipment, reducing assembly time and enhancing operational reliability.
Specification Summary & Compliance
This set screw adheres to ASME B18.3 specifications, with precise UNC thread standards and Class 3A thread fit for optimal dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no hazardous substances are used. The manufacturing process meets rigorous quality controls for consistent performance in industrial applications.
