Why choose Grade 5 steel screws?
These screws deliver strong clamping force with reliable performance in secure joints. The 5/16-18 thread pitch is a common choice for robust assemblies, and the 6-inch length provides substantial engagement in thicker materials. Being plain steel, they accept field coatings or paints to match your project, or can be used as-is where a bare metal finish is preferred.
Ideal for machinery, construction, automotive, and equipment installations where strength and reliability matter. Built in the USA, these screws meet quality standards you can trust and offer consistent performance batch after batch.
