Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit for precise, vibration-resistant fastening in demanding applications
- Enhanced corrosion resistance from the black-oxide finish on alloy steel, extending service life in industrial environments
- Optimized torque transmission via the 3/16" hex drive and headless design, allowing flush installation and high clamping force
- Reliable coarse UNC threading (3/8"-16) for quick assembly and reduced cross-threading risk in right-hand applications
- Exceptional durability with Rockwell C45 hardness, resisting wear and deformation under heavy loads
- Flat tip design provides secure contact with shafts or components, minimizing slippage and surface damage
- Full regulatory compliance including RoHS 3 and REACH, ensuring safe use in global markets
Professional Applications & Engineering Value
This 3/8"-16 UNC set screw is engineered to address critical challenges in industrial machinery, automotive assemblies, and precision equipment. The black-oxide alloy steel construction combats rust and wear, while the Class 3A thread fit ensures tight tolerances that prevent loosening under vibration—a common failure point in rotating components. The headless hex drive design allows for seamless integration into collars, pulleys, and gears, providing maximum grip without protruding hardware. With coarse threads facilitating rapid installation and the flat tip distributing pressure evenly, this screw delivers reliable positioning and torque retention in high-stress environments, from conveyor systems to motor shafts.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit per UNC standards, with a diameter of 0.375" and coarse 16 TPI spacing. It meets ASME B18.3 and ASTM F912 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted hazardous substances for safe industrial use worldwide.
