Product Description

The 1/2-13x7/8 Hex Bolt, compliant with 1/2-13 UNC threading standards, is a heavy-duty fastener designed for industrial applications requiring high tensile strength and durability. This 7/8-inch-long machine screw features a 1/2-inch nominal diameter with 13 threads per inch (UNC coarse thread) for secure mechanical joining in structural assemblies. Constructed from grade-specific steel or corrosion-resistant materials, it operates reliably within temperature ranges of -40°C to 120°C and withstands vibration-intensive environments. Commonly used in construction equipment, automotive frames, and machinery manufacturing, this hex-head bolt enables direct mounting through standard 1/2-inch threaded holes. Key advantages include zinc-plated or hot-dip galvanized surface treatments for rust prevention, though prolonged exposure to marine environments may require additional coatings. The hexagonal drive design ensures compatibility with standard wrench sizes for simplified installation.
