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

The 5/8"‑11 × 5" Grade 8 dome head plow bolt (No. 3) is built for extreme‑duty 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 bolt features a smooth dome head to reduce wear and interference, along with a square neck that prevents 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 resistance, impact strength, and long service life are required.
