Fractional Size No. 3 Dome Head Grade 8 Plow Bolt with Plain Finish

Fractional Size No. 3 Dome Head Grade 8 Plow Bolt with Plain Finish

Fractional Size No. 3 Dome Head Grade 8 Plow Bolts with Plain Finish are engineered for extreme-duty fastening in high-impact agricultural, construction, and heavy equipment applications. Designed to handle severe vibration, heavy loads, and abrasive environments, these high-strength plow bolts provide dependable performance where lesser fasteners may fail. The No. 3 dome head configuration offers a smooth, low-profile surface while delivering the clamping force required for demanding structural assemblies.

Grade 8 Strength for Maximum Load Capacity

Manufactured from heat-treated alloy steel, Grade 8 plow bolts offer significantly higher tensile strength and shear resistance than Grade 5 or standard carbon steel fasteners. This makes them ideal for securing cutting edges, grader blades, plow shares, skid shoes, and heavy wear components. Grade 8 hardware is designed to withstand extreme stress, making it the preferred choice for road maintenance equipment, mining machinery, and earthmoving attachments.

No. 3 Dome Head Design with Secure Square Neck

The No. 3 dome head features a rounded, smooth profile that reduces material buildup and minimizes surface wear in abrasive environments. This head style sits flush or slightly below the mounting surface, helping protect equipment and maintain smooth operation. Beneath the head, the square neck locks securely into place, preventing rotation during installation. This anti-spin feature allows for efficient tightening from the nut side, even in high-torque applications.

Plain Finish for Controlled Environments

The plain, uncoated steel finish maintains the raw strength of the alloy steel material. Best suited for dry or controlled environments, this finish provides a cost-effective solution where additional corrosion resistance is not required.
