5/8"‑11 × 1‑1/2" Grade 8 Dome Head Plow Bolt No. 3 – 150,000 PSI, Plain Finish

The 5/8"‑11 × 1‑1/2" Grade 8 dome head plow bolt (No. 3) is designed for heavy‑duty structural and earth‑moving applications where high strength and a smooth, low‑profile head are required. Manufactured to a Grade 8 rating with a minimum tensile strength of 150,000 PSI, this bolt features a dome (round) head and square neck to prevent rotation during installation. Supplied with a plain (uncoated) finish, it is ideal for use in grader blades, plow assemblies, heavy equipment, and wear‑surface applications where maximum strength, durability, and flush mounting are critical.
