Plow Bolts

Plow Bolts for Heavy-Duty Agricultural and Earthmoving Applications

Plow bolts are specialized fasteners engineered for demanding environments where strength, durability, and a smooth surface finish are critical. Commonly used in agricultural equipment, construction machinery, and earthmoving applications, plow bolts are designed to secure wear parts such as plow blades, cutting edges, grader blades, and scraper bars to heavy equipment frames.

Design Features Built for Performance

Plow bolts are easily recognized by their countersunk flat head and square neck beneath the head. The countersunk design allows the bolt head to sit flush with the surface, preventing interference with soil, debris, or material flow during operation. The square neck locks into the mating hole, preventing the bolt from spinning during installation and ensuring a secure, vibration-resistant hold under extreme working conditions.

Strength Grades and Material Options

Plow bolts are typically manufactured from high-strength carbon or alloy steel and are commonly available in Grade 5 and Grade 8 options. Grade 5 plow bolts provide excellent tensile strength for standard agricultural and light construction equipment, while Grade 8 plow bolts are designed for maximum load capacity, impact resistance, and extended service life in severe-duty applications. Heat-treated construction ensures durability under repeated shock and abrasive conditions.

Applications Across Multiple Industries

Plow bolts are widely used in farming equipment such as plows, discs, cultivators, and harrows, as well as in construction and road maintenance equipment including graders, bulldozers, and snowplows. Their flush-mount design reduces wear on both the fastener and the attached component, extending equipment life and improving operational efficiency.
