Product Description

The 1/2-13x2-3/8 bolts are coarse thread hex fasteners designed for heavy-duty industrial applications such as machinery assembly, structural frameworks, and equipment manufacturing. These heavy-duty machine screws feature a 1/2-inch diameter with 13 threads per inch (coarse thread) and a 2-3/8-inch shank length. Constructed from high-strength steel with corrosion-resistant coatings, they operate reliably in temperatures from -40°F to 500°F (-40°C to 260°C). The hexagonal head enables secure torque application using standard wrenches. Ideal for high-stress environments, they excel in load-bearing joints requiring shear strength and vibration resistance. While optimized for rugged use, their coarse threading may require supplementary locking mechanisms in dynamic applications. Typical industries include automotive, construction, and industrial equipment. Key advantages include durability, ease of installation, and compatibility with thick materials.
