Professional Applications & Engineering Value

Engineered for heavy-duty industrial and agricultural equipment, these Grade 5 plow bolts solve critical fastening challenges in high-vibration environments. The zinc-plated steel construction provides essential corrosion protection for outdoor machinery and implements, while the square neck design eliminates rotational movement that can loosen standard fasteners. The fully threaded UNC coarse spacing ensures rapid installation and superior grip in thick materials, making them ideal for plow shares, bulldozer blades, and construction attachments. The combination of 120,000 psi tensile strength and Rockwell C25 hardness delivers the necessary durability to withstand impact loads and abrasive conditions common in earth-moving operations.
