Professional Applications & Engineering Value
These zinc-plated steel flat head screws deliver exceptional performance in industrial settings where corrosion resistance and structural integrity are paramount. The UNC coarse thread design ensures rapid installation in metal, plastic, and wood substrates, while the fully threaded configuration provides maximum clamping force along the entire 2" length. The Phillips No. 2 drive offers reliable torque transmission without stripping, and the 82° countersink angle creates a seamless surface profile ideal for machinery, electrical enclosures, and assembly lines. Engineered to withstand vibration and mechanical stress, these flat head screws maintain their 60,000 psi tensile strength in demanding applications including automotive manufacturing, industrial equipment maintenance, and construction projects.
Specification Summary & Compliance
Manufactured to exact inch system dimensions with Class 2A thread fit tolerance for precision assembly. The UNC coarse thread (6-32 size) follows standardized spacing and right-hand thread direction. Compliant with ASME B18.6.3 manufacturing specifications for dimensional accuracy and performance. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in restricted substance-sensitive applications.
