SAE J429 grade 8 zinc plated full thread UNC galvanized plow bolt
Plow bolts feature a countersunk, flat head, square neck, and unified thread pitch. They are commonly used in road graders, scoop shovels, and other heavy-duty industrial equipment where a flat, smooth surface is required. Grade-5 plow bolts are made from a medium-grade, heat-treated carbon steel, whereas Grade-8 plow bolts are made from heat-treated alloy steel and provide greater tensile and proof load strength. The most popular uses for Grade-8 are bulldozers and snowplow blades.
