National Mfg N301-259 Cold Rolled Smooth Rod 3/16x36 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N301-259 is a cold rolled smooth steel rod measuring 3/16 inches in diameter and 36 inches in length. Cold rolled steel delivers higher yield strength, greater hardness, and tighter dimensional tolerances than hot rolled steel, making this rod well suited for applications that require consistent forming and reliable weld joints. At 0.28 pounds, it is lightweight and easy to handle on the job site. This rod meets ASTM A510 standards and is rated for exterior use. It is installed by general contractors, fencing installers, and tradespeople across a range of structural and fabrication tasks.

This smooth rod is designed for fencing, supports, railing, sign posts, framework, and other industrial applications. Its consistent cold rolled profile makes it a practical choice for both residential and light commercial projects where a uniform, weldable steel rod is needed. The 36-inch length suits standard framing and support layouts without requiring additional cutting in most applications. It is sold individually and is appropriate for use in exterior environments.

Key Features

• Cold rolled steel construction provides higher yield strength and hardness compared to hot rolled alternatives
• Meets ASTM A510 standard for steel wire rod and coarse round wire
• Rated for exterior applications
• Excellent forming and welding characteristics for fabrication work
• 3/16 inch diameter with consistent dimensional tolerance across the 36-inch length

Compatibility

Designed for general-purpose use in fencing, railing, sign post, support, and framework applications where a cold rolled smooth steel rod meeting ASTM A510 is specified.

Installation Notes

Installation is typically performed by general contractors, fencing installers, or fabricators using standard metalworking tools. Cut to length using an appropriate metal cutting tool if needed, and de-burr cut ends before assembly. Follow applicable local building codes and OSHA safety guidelines when working with structural support components. Wear appropriate personal protective equipment when cutting or welding this rod.
