Product Description

The 1/2-13 Hex Bolt, a 4 Inch UNC Bolt with Coarse Thread Fastener design, is a heavy-duty threaded fastener engineered for high-tensile applications in industrial construction, machinery assembly, and automotive sectors. Featuring a 1/2-inch nominal diameter, 13 threads per inch (UNC coarse thread), and a 4-inch shank length, it provides robust clamping force and vibration resistance. The hex head design ensures secure torque application, compatible with standard wrenches. Constructed from grade 5 steel with a zinc-plated finish, it withstands temperatures from -20°C to 120°C and offers corrosion resistance for harsh environments. Key advantages include durability, standardized compatibility, and ease of installation, though improper torque application may risk thread stripping. Ideal for structural joints, equipment frames, and load-bearing assemblies requiring coarse-thread reliability.
