Professional Applications & Engineering Value
These 316 stainless steel flat head screws deliver exceptional performance in demanding industrial environments where corrosion resistance and structural integrity are paramount. The combination of passivated finish and UNC coarse threading ensures reliable fastening in chemical processing equipment, marine hardware, and food processing machinery where exposure to corrosive elements is constant. The fully threaded design provides maximum grip length while the 82° countersink angle allows for flush mounting in precision assemblies. With 70,000 psi tensile strength, these screws maintain clamping force under vibration and load stress, making them ideal for structural applications requiring long-term reliability and minimal maintenance in challenging operating conditions.
Specification Summary & Compliance
This 1/2"-13 UNC flat head screw features precise Class 2A thread fit according to ASME B18.6.3 standards, ensuring consistent dimensional accuracy and proper engagement. The manufacturing process adheres to strict quality controls with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 2" length and coarse thread spacing provide optimal fastening performance while maintaining specification integrity across production batches for reliable industrial application.
