Professional Applications & Engineering Value

This 3/8"-16 x 10" 18-8 stainless steel flat head screw is engineered to address critical challenges in industrial applications where corrosion resistance and structural integrity are paramount. The passivated finish enhances the natural corrosion-resistant properties of 18-8 stainless steel, making it suitable for outdoor, marine, or chemical-exposed environments. Its UNC coarse thread and Class 3A fit provide excellent grip in soft materials like wood or plastic, while the fully threaded design ensures uniform stress distribution. The flat head with 82° countersink allows for seamless integration in machinery, construction, and assembly lines, preventing snagging and maintaining aerodynamic or aesthetic surfaces. With a Rockwell B55 hardness and 70,000 psi tensile strength, it withstands heavy loads and repetitive stress, reducing maintenance needs and downtime in heavy-duty settings.

Specification Summary & Compliance

This screw adheres to ASME B18.3 specifications, ensuring dimensional accuracy and performance reliability. The UNC thread with Class 3A fit provides tight tolerances for precision assembly, while the coarse thread spacing facilitates quick installation. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting environmentally responsible manufacturing practices.
