Model 5/8-11*4-1/2 High-Strength Hex Bolt Grade 8 Zinc-Plated Fastener For Automotive

5/8-11x4.5 bolt
5/8-11 threaded rod
4.5 inch hex bolt
5/8-11*4-1/2
5/8-11x4.5 heavy-duty hex bolt with 4.5 inch length, crafted from durable 5/8-11 threaded rod for industrial fastening applications.

Product Description

The 5/8-11x4.5 bolt is a threaded fastener designed for heavy-duty industrial applications, compatible with 5/8-11 threaded rod systems. This 4.5-inch hex bolt features a standard hex head for easy installation using standard wrenches or sockets. With a nominal diameter of 5/8" (15.875 mm) and 11 threads per inch, it ensures high tensile strength and secure mechanical connections. Made from Grade 5 or Grade 8 carbon steel (optional), it operates reliably in temperature ranges from -30°C to 120°C and withstands vibration-resistant clamping force up to 120,000 PSI. Widely used in construction, machinery assembly, and structural frameworks, its zinc-plated surface offers moderate corrosion resistance. Notable advantages include uniform threading precision and load-bearing capacity, though prolonged exposure to moisture may accelerate oxidation without protective coatings.
