Fractional Size No. 3 Head Grade 5 Plow Bolt with Clear Cr3 Zinc Plating

Fractional Size No. 3 Head Grade 5 Plow Bolt with Clear Cr3 Zinc Plating

Fractional Size No. 3 Head Grade 5 Plow Bolts with Clear Cr3 Zinc Plating are built for rugged, high-load fastening in agricultural, construction, and heavy equipment applications. Designed with a wide, countersunk No. 3 head and square neck, these plow bolts provide a smooth, flush surface while delivering the strength required for demanding field conditions. The addition of Clear Cr3 zinc plating enhances corrosion resistance, making them a reliable choice for both indoor and light outdoor use.

Grade 5 Heat-Treated Strength for Heavy-Duty Performance

Manufactured from medium carbon steel and heat-treated to meet SAE Grade 5 standards, these plow bolts offer superior tensile strength and shear resistance compared to standard low carbon fasteners. Grade 5 hardware is engineered to withstand vibration, shock loads, and repeated stress, making it ideal for securing cutting edges, moldboards, grader blades, skid shoes, and wear plates. The increased strength ensures dependable performance in high-impact environments where equipment reliability is critical.

No. 3 Countersunk Head with Anti-Rotation Square Neck

The No. 3 plow bolt head features a flat, countersunk profile that sits flush with the material surface after installation. This design prevents material buildup and reduces interference with moving components. Beneath the head, the square neck locks into place within the mounting hole, preventing the bolt from spinning during tightening. This allows for efficient installation using a wrench or impact tool on the nut side only.

Clear Cr3 Zinc Plating for Corrosion Protection

The Clear Cr3 (trivalent chromium) zinc plating provides a bright, clean finish while offering enhanced protection against rust and oxidation. This RoHS-compliant coating improves durability in moderately corrosive environments without compromising mechanical strength.
