Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating, extending service life in harsh industrial environments
- Exceptional holding power from Rockwell C45 hardness, preventing deformation under high torque applications
- Precise thread engagement with Class 3A fit, ensuring reliable fastening without cross-threading
- Easy installation and removal using standard 3/16" hex tools, reducing maintenance time and tooling costs
- Maximum surface contact from cup point design, providing superior grip and resistance to vibration loosening
- Industry-standard compatibility with UNC coarse threads, facilitating replacements across equipment systems
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing operations
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance where vibration resistance and corrosion protection are paramount. The Class 3A thread fit maintains precise tolerances for repeated assembly/disassembly cycles in machinery, automotive, and heavy equipment applications. The cup point design bites securely into shaft materials, preventing component slippage in high-torque environments. Manufactured to ASME B18.3 specifications, these headless set screws provide flush mounting in confined spaces while the coarse UNC thread enables rapid installation in production line settings. The combination of Rockwell C45 hardness and protective coating ensures reliable performance in demanding conditions where standard fasteners would fail.
Specification Summary & Compliance
Precision-engineered with Class 3A thread fit per ASME standards, maintaining tight tolerances for critical applications. The 3/8"-16 UNC coarse thread specification ensures compatibility with standard components. Manufacturing complies with ASME B18.3 where applicable ASTM F912 requirements are met. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and global market acceptability.
