• Enhanced corrosion resistance from the black-oxide finish on alloy steel, extending service life in demanding environments
• Optimal material strength with Rockwell C45 hardness, ensuring durability under high-stress applications
• Secure, flush mounting thanks to the headless design and 118° cone point for deep, reliable component engagement
• Easy installation and removal with the 5/32" hex drive, compatible with standard tools for efficient maintenance
• Wide compatibility with UNC coarse threads (5/16"-18), ideal for general-purpose industrial fastening
• Regulatory peace of mind meeting ASME B18.3, ASTM F912, RoHS 3, and REACH standards for quality and safety

Professional Applications & Engineering Value

This 5/16"-18 UNC set screw is engineered to address critical challenges in industrial assemblies, such as component slippage and vibration-induced loosening. The black-oxide alloy steel construction provides excellent resistance to wear and environmental factors, while the Class 3A thread fit ensures tight tolerances for secure fastening in machinery, automotive, and equipment manufacturing. The 118° cone point and headless hex drive design allow for deep penetration and flush installation, making it ideal for securing gears, pulleys, and collars without protruding hardware. By combining high hardness (Rockwell C45) with compliance to ASME B18.3 and other standards, this screw delivers reliable performance in heavy-duty applications, reducing maintenance needs and enhancing assembly longevity.

Specification Summary & Compliance

This set screw features a 5/16"-18 UNC coarse thread with Class 3A thread fit for high precision, a 5/32" hex drive, and a cone point with 118° angle.
