Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit for precise, vibration-resistant fastening in demanding applications
- Exceptional durability from Rockwell C45 hardness alloy steel, providing excellent resistance to wear and deformation
- Corrosion-resistant black-oxide finish extends service life and maintains performance in harsh industrial environments
- High-torque capability with 3/8" hex drive design for secure installation and removal without stripping
- Optimal engagement through UNC coarse threads that resist loosening under dynamic loads and vibration
- Space-saving headless design allows for flush mounting where clearance is limited
- Reliable flat tip creates maximum surface contact for secure positioning of components
Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical performance in industrial applications where vibration resistance and precise component positioning are essential. The UNC coarse thread configuration combined with Class 3A thread fit ensures reliable engagement in machinery, automotive assemblies, and heavy equipment where loosening under dynamic loads can cause catastrophic failure. The headless hex drive design with 3/8" drive size provides optimal torque transmission while maintaining a low profile for space-constrained applications. Engineered with Rockwell C45 hardness, this set screw maintains its structural integrity under repeated stress, making it ideal for permanent or semi-permanent fastening solutions in manufacturing, construction, and power transmission systems.
Specification Summary & Compliance
This set screw features 3/4"-10 UNC coarse threads with Class 3A thread fit for precision tolerance. Manufactured to ASME B18.3 specifications and ASTM F912 standards, ensuring consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications with strict chemical substance restrictions.
