Product Description

The 1/2-13*5 industrial bolt series includes three versatile variants: the 1/2-13 Hex Bolt, 1/2-13x5 Bolt, and 1/2-13 Carriage Bolt, designed for heavy-duty fastening in construction, automotive, and machinery sectors. Featuring a 1/2-inch diameter, 13 threads per inch, and a 5-inch shank length, these bolts are crafted from high-grade steel with optional zinc plating for corrosion resistance. They operate reliably in temperatures ranging from -40°C to 150°C and offer exceptional tensile strength (up to 150 ksi) for load-bearing applications. The hexagonal head of the Hex Bolt enables tool-driven installation, while the Carriage Bolt’s smooth domed head suits aesthetic or safety-critical assemblies. Drawbacks include the need for pre-drilled holes and torque calibration during installation. Surface-coated variants enhance durability in humid or chemically exposed environments. These bolts comply with ASTM A307 standards, ensuring compatibility with industrial fastening systems.
