Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 316 stainless steel rounded head screws deliver exceptional performance where corrosion resistance is critical. The fully threaded 6-32 UNC coarse pitch design ensures maximum thread engagement and vibration resistance in assemblies subjected to dynamic loads. The passivated finish creates an additional protective oxide layer, significantly enhancing the screw's resistance to chemical attack and oxidation in processing equipment, marine hardware, and outdoor installations. The combination of 80,000 psi tensile strength and Rockwell B85 hardness provides reliable clamping force maintenance in structural applications while the Phillips No. 2 drive and rounded pan head profile facilitate efficient installation in confined spaces. These screws are particularly valuable in chemical processing, food equipment, and marine applications where both mechanical integrity and environmental durability are paramount requirements.
