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

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