Product Description

The 1/2-13x1-1/4 Hex Bolt is a coarse-threaded fastener featuring a 1/2-inch nominal diameter, 13 threads per inch (1/2-13 UNC), and a 1-1/4-inch shank length. Designed for heavy-duty applications, this carbon steel bolt offers high tensile strength (Grade 5 or higher) and is coated with zinc or phosphate for corrosion resistance. Compatible with standard 1/2-13 UNC nuts, it supports torque capacities up to 150 lb-ft, making it ideal for construction, automotive, and industrial machinery assemblies. Operating effectively in temperatures ranging from -20°F to 250°F (-29°C to 121°C), its hexagonal head ensures secure wrench engagement. While durable, prolonged exposure to extreme moisture may require additional protective coatings. Thread engagement depth exceeds 1 inch for optimal load distribution.
