Professional Applications & Engineering Value
This 5/16"-18 UNC Class 3A hex headless set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. Crafted from 18-8 stainless steel, it provides excellent resistance to rust and chemical exposure, making it suitable for applications in machinery, automotive, and outdoor equipment where moisture or corrosive agents are present. The Class 3A thread fit and coarse thread spacing ensure a precise, secure grip on shafts, collars, and other rotating parts, minimizing loosening from vibration. Its headless design with a flat tip allows for flush mounting, reducing protrusion risks in compact assemblies. The 5/32" hex drive enables efficient torque transfer during installation, streamlining maintenance and enhancing operational reliability in demanding settings.
Specification Summary & Compliance
This set screw features a 5/16"-18 UNC thread with Class 3A fit for high precision and coarse thread spacing for quick assembly. It adheres to ASME B18.3 manufacturing standards and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and quality consistency in industrial use.
