Professional Applications & Engineering Value

This 3/8"-16 UNC Rounded Fillister Head Screw is engineered to address critical industrial fastening challenges. Its 18-8 Stainless Steel material and passivated finish provide excellent resistance to corrosion and oxidation, making it ideal for applications in marine, chemical processing, and food equipment where moisture and chemicals are prevalent. The coarse threading (UNC) and Class 2A thread fit ensure reliable engagement in various materials, reducing installation time and preventing thread stripping. The slotted drive and high, narrow rounded fillister head offer superior torque transmission and a low-profile design for spaces with limited clearance. Commonly used in machinery assembly, automotive components, and electrical enclosures, this screw delivers consistent tensile strength and durability, supporting long-term operational integrity in industrial fasteners systems.
