Professional Applications & Engineering Value
These 12-24 UNC flat head screws in 18-8 Stainless Steel deliver critical performance in demanding industrial settings. The combination of 80,000 psi tensile strength and Rockwell B80 hardness addresses common failure points in high-vibration applications, while the passivated finish significantly enhances corrosion resistance against moisture, chemicals, and outdoor exposure. The fully threaded coarse spacing ensures maximum thread contact in softer materials or when minimal engagement depth is available, preventing stripping and maintaining clamp force. Engineers specify these ASME B18.6.3 compliant fasteners for machinery, electrical enclosures, and structural assemblies where reliable fastening solutions are non-negotiable.
Specification Summary & Compliance
This flat head screw features precise Class 2A thread fit with 12-24 UNC coarse thread specifications, 2" length, and standard 82° countersink angle. Manufacturing complies with ASME B18.6.3 standards for dimensional accuracy and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to strict environmental and safety regulations for industrial components.
