Fractional Size No. 3 Head Grade 5 Plow Bolt with Plain Finish

Fractional Size No. 3 Grade 5 Plow Bolts with Plain Finish

Fractional Size No. 3 Grade 5 Plow Bolts with Plain Finish are engineered for heavy-duty fastening in demanding agricultural, construction, and industrial environments. Designed with a countersunk flat head and square neck, these high-strength plow bolts provide a flush surface installation while delivering superior holding power. Commonly used on cutting edges, grader blades, plows, and heavy equipment attachments, Grade 5 plow bolts offer the durability required for high-impact and high-load applications.

Grade 5 Strength for Heavy Equipment Applications

Manufactured from medium carbon steel and heat-treated to meet Grade 5 specifications, these plow bolts provide increased tensile strength compared to standard low carbon fasteners. This enhanced strength makes them ideal for securing wear parts on tractors, snowplows, loaders, scrapers, and road maintenance equipment. The Grade 5 rating ensures dependable performance under vibration, shock loads, and continuous operational stress.

Countersunk Head and Square Neck Design

The defining feature of a No. 3 plow bolt is its flat, countersunk head, which sits flush with the surface once installed. This design prevents material buildup and reduces wear on moving components. The square neck beneath the head locks securely into place when tightened, preventing the bolt from turning during installation. This allows for efficient fastening in high-torque applications using a nut on the opposite side.

Plain Finish for Dry and Controlled Environments

The plain, uncoated steel finish is suitable for indoor or dry applications where corrosion resistance is not a primary concern. This finish provides a cost-effective solution while maintaining the mechanical strength required for structural fastening.
