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

The 5/8"‑11 × 3" Grade 8 dome head plow bolt (No. 3) is designed for severe, high‑impact applications where maximum strength and a flush, low‑profile head are essential. Manufactured to Grade 8 specifications with a minimum tensile strength of 150,000 PSI, this fastener features a smooth dome head to minimize wear and surface 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 strength, durability, and resistance to abrasion are critical.
