Professional Applications & Engineering Value

These 3/8"-16 UNC coarse thread screws are engineered to address common industrial challenges, such as vibration loosening and material fatigue. The passivated 18-8 stainless steel provides excellent resistance to oxidation and chemical exposure, making them suitable for demanding sectors like marine equipment, food processing machinery, and structural assemblies. The partially threaded configuration ensures optimal grip in applications where full threading is unnecessary, reducing stress concentration and enhancing joint reliability. With a Rockwell B70 hardness and robust rounded head design, these screws maintain integrity in high-torque scenarios, while the Phillips drive facilitates quick installation in automated or manual settings, streamlining production workflows.

Specification Summary & Compliance

This rounded head screw features precise UNC coarse threads with a Class 2A thread fit for consistent dimensional accuracy. It meets ASME B18.6.3 specifications for mechanical and dimensional requirements, ensuring interoperability with standard components. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting sustainable procurement practices.
