They find their application in heavy machinery such as road graders and scoop shovels, where a smooth, flat surface is essential. These bolts, when zinc plated, offer robust resistance to corrosion. Constructed from medium carbon steel, Grade-5 plow bolts are identifiable by their three radial bars on the head marking.

Countersunk, Flat Head: Plow bolts have a flat head that is countersunk, allowing them to lie flush with the surface of the material they're fastened to. This design is crucial for applications where a smooth surface is necessary to avoid catching or snagging, such as on the blades of a plow.\u003c\/li\u003e\n\u003cli\u003eSquare Neck: Directly beneath the head of a plow bolt is a square neck, which prevents the bolt from turning as it's tightened. This feature is particularly useful in materials that don't allow for a deep countersink, providing a locking mechanism that holds the bolt steady during tightening and use. Unified Thread Pitch: Plow bolts have a standardized thread pitch, which ensures compatibility with nuts and threaded holes designed for a specific size and type of bolt. This standardization facilitates easier maintenance and replacement.\u003c\/li\u003e\n\u003cli\u003eSquare Neck: Directly beneath the head of a plow bolt is a square neck, which prevents the bolt from turning as it's tightened.
