1‑1/4"‑7 × 6" Grade 8 Dome Head Plow Bolt No. 3 – 150,000 PSI, Plain Finish

The 1‑1/4"‑7 × 6" Grade 8 dome head plow bolt (No. 3) is built for extreme‑duty, high‑impact applications where maximum strength, durability, and flush mounting are essential. Manufactured to Grade 8 specifications with a minimum tensile strength of 150,000 PSI, this fastener features a smooth, rounded dome head designed to minimize 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, this plow bolt is ideal for plow blades, grader edges, heavy equipment, and earth‑moving machinery where superior shear resistance, impact strength, and long service life are critical.
