Professional Applications & Engineering Value

This zinc-plated steel Phillips pan head screw delivers exceptional engineering value for industrial applications where corrosion resistance and mechanical reliability are paramount. The 3/8"-16 UNC coarse thread configuration provides rapid installation and superior vibration resistance in machinery assembly, structural frameworks, and heavy equipment manufacturing. The combination of 60,000 psi tensile strength and Rockwell B70 hardness ensures these fully threaded screws maintain integrity under dynamic loads and repeated stress cycles. The rounded pan head profile distributes clamping force evenly while the zinc plating creates a protective barrier against oxidation and environmental degradation, making these industrial screws ideal for outdoor applications, manufacturing facilities, and maintenance operations requiring long-term fastening solutions.
