Product Description

The 1/2-13 Hex Bolt and 3/4" Cap Screw is a high-strength UNC Threaded Rod designed for robust mechanical fastening in industrial applications. Featuring a 1/2" diameter shaft with 13 threads per inch (UNC standard) and a 3/4" head length, it delivers reliable torque transmission for heavy-duty assemblies. Constructed from grade-8 hardened steel, it operates in extreme temperatures (-50°C to 300°F) and resists corrosion through zinc-plated surface treatment. Widely used in construction, machinery, and automotive sectors for structural connections requiring 180 ksi tensile strength. Key advantages include vibration resistance and compatibility with standard 3/4" hex tools, though installation requires precise torque calibration to prevent overtightening. Thread engagement depth exceeds 1.5x diameter for optimal load distribution. Packaging includes anti-seize lubrication for extended service life in harsh environments.
