This hex cap screw is a Grade 8 fastener, manufactured from alloy steel, and zinc plated for corrosion resistance. Grade 8 hex cap screws offer 150,000 PSI tensile strength, making them suitable for high-stress applications. The zinc finish provides a barrier against rust and oxidation, extending the fastener’s service life compared to plain steel options.
Used in heavy equipment assembly, engine repair, and structural applications where high strength and resistance to shear forces are required. The zinc plating retards surface rust, maintaining appearance and thread function in typical industrial environments over time.
