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

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