7/8"‑9 × 3" Grade 8 Dome Head Plow Bolt No. 3 – 150,000 PSI, Plain Finish

The 7/8"‑9 × 3" Grade 8 dome head plow bolt (No. 3) is engineered for severe‑duty, high‑impact applications where maximum strength and a smooth, flush mounting profile are essential. Manufactured to Grade 8 specifications with a minimum tensile strength of 150,000 PSI, this bolt features a rounded dome head to reduce wear and surface interference, along with a square neck that locks into the mating hole to prevent rotation during installation. Supplied in a plain (uncoated) finish, it is commonly used in plow blades, grader edges, snow‑removal equipment, and heavy earth‑moving machinery where superior shear resistance, durability, and long service life are critical.
