5/8"‑11 × 2‑3/4" Grade 8 Dome Head Plow Bolt No. 3 – 150,000 PSI, Plain Finish

The 5/8"‑11 × 2‑3/4" Grade 8 dome head plow bolt (No. 3) is engineered for severe‑duty applications where high strength and a flush, low‑profile head are essential. Manufactured to Grade 8 standards with a minimum tensile strength of 150,000 PSI, this fastener features a smooth dome head to reduce wear and snagging, along with a square neck that prevents rotation during installation. Supplied with a plain (uncoated) finish, it is ideally suited for plow blades, grader edges, earth‑moving equipment, and heavy machinery where exceptional shear resistance, durability, and long service life are required.
