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

The 3/4"‑10 × 4‑1/2" Grade 8 dome head plow bolt (No. 3) is engineered for extreme‑duty, high‑wear applications where maximum strength, durability, and a flush mounting profile are critical. Manufactured to Grade 8 specifications with a minimum tensile strength of 150,000 PSI, this fastener features a smooth, rounded dome head to reduce abrasion 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 widely used in plow blades, grader edges, snow removal equipment, and heavy earth‑moving machinery where superior shear resistance, impact toughness, and long service life are required.
