National Mfg N179-770 Zinc Smooth Rod 5/16x36 Inch

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N179-770 is a zinc-plated smooth rod measuring 5/16 inch in diameter and 36 inches in length. It is designed primarily for use as an axle on wagons, carts, and similar DIY fabrication projects. The zinc plating provides a corrosion-resistant finish suited for general workshop and utility applications. This rod can be drilled, cut, heated, and shaped to fit a wide range of project requirements. It is not recommended for welding, as the zinc plating releases harmful fumes when exposed to welding heat. Sold in a package of 3, it is a practical stock item for contractors, maintenance techs, and experienced DIYers working on custom builds or repairs.

This smooth rod is well suited for light-duty mechanical applications where a straightforward, machinable steel rod with a zinc finish is needed. Typical uses include axle fabrication for hand carts, garden wagons, utility dollies, and other shop-built rolling equipment. The 36-inch length provides enough stock for multiple cuts depending on the project layout. The 5/16-inch diameter fits standard axle hardware and common bore sizes found in wheel hubs used in DIY and light fabrication work.

Installation Notes

Cut to length using a hacksaw or angle grinder before fitting into wheel hubs or brackets. When heating or shaping, work in a well-ventilated area and use appropriate personal protective equipment. Do not weld this rod — zinc plating produces toxic fumes under welding temperatures. Secure axle ends with appropriate retaining clips, cotter pins, or nuts as required by the project design.
