Professional Applications & Engineering Value
These 12-24 UNC flat head screws are engineered to address common industrial challenges, such as vibration loosening and environmental degradation. Made from passivated 18-8 stainless steel, they provide excellent resistance to corrosion, making them suitable for applications in marine, chemical processing, and outdoor equipment. The coarse UNC threads and Class 2A fit ensure quick, reliable fastening in metals and plastics, reducing installation time and maintenance needs. With an 82° countersink angle and flat head design, they sit flush in pre-drilled holes, minimizing protrusions in machinery and enclosures. Ideal for assembly lines, automotive components, and electrical housings, these screws deliver consistent performance where high tensile strength and regulatory compliance are critical.
Specification Summary & Compliance
This product features precise Class 2A thread fit and UNC coarse threading with a size of 12-24 and length of 5/8". It meets ASME B18.6.3 specifications for dimensional accuracy and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring safety and environmental responsibility in industrial applications.
