3/4"‑10 × 2‑1/4" Grade 8 Dome Head Plow Bolt No. 3 – 150,000 PSI, Plain Finish

The 3/4"‑10 × 2‑1/4" Grade 8 dome head plow bolt (No. 3) is built for severe‑duty, high‑impact applications where maximum strength and a smooth, flush mounting profile are required. Manufactured to Grade 8 specifications with a minimum tensile strength of 150,000 PSI, this bolt features a rounded dome head designed to minimize wear and surface interference, along with a square neck that locks into place 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.
