Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N215-335 is a cold rolled smooth steel rod measuring 5/16 inches in diameter and 48 inches in length. Cold rolled construction delivers tighter dimensional tolerances and a cleaner surface finish compared to hot rolled alternatives, making it well suited for applications where appearance and fitment precision matter. The rod meets ASTM A51 standards and exhibits excellent forming and welding characteristics, allowing tradespeople and fabricators to cut, bend, and weld it into finished assemblies with minimal prep work. Each package contains 2 rods and weighs 2.1 pounds total.

This smooth rod is designed for a range of light structural and industrial fabrication applications including fencing, supports, railing, sign posts, and general framework. It is commonly used by contractors, ironworkers, and skilled tradespeople on both residential and light commercial projects. The consistent cold rolled finish makes it a practical choice wherever a clean, weldable steel rod is needed for custom fabrication or repair work.
