7/8"‑9 × 2‑1/2" Grade 8 Dome Head Plow Bolt No. 3 – 150,000 PSI, Plain Finish

The 7/8"‑9 × 2‑1/2" Grade 8 dome head plow bolt (No. 3) is engineered for severe‑duty, high‑impact applications where maximum strength and a smooth, flush mounting profile are essential. Manufactured to Grade 8 specifications with a minimum tensile strength of 150,000 PSI, this fastener features a rounded dome head designed to reduce 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, this plow bolt is ideal for plow blades, grader edges, snow removal equipment, and heavy earth‑moving machinery where superior shear resistance, durability, and long service life are critical.
