How to Choose the Best Plow Bolts
Bolt Material and Strength
Consider the material of the plow bolt, as it directly impacts its durability and resistance to wear. High-strength steel alloys are common and recommended for heavy-duty applications. Look for grades like Grade 5 or Grade 8, which indicate superior tensile strength and resistance to shearing forces. Stainless steel options offer excellent corrosion resistance, ideal for harsh weather conditions, though they may be less strong than hardened steel.
Head Style and Size
Plow bolts typically feature a countersunk or mushroom head to sit flush with the plow surface, preventing snags and damage. The most common head style is the "square neck" or "ribbed neck" bolt, designed to prevent the bolt from turning when the nut is tightened. Ensure the bolt diameter and length are appropriate for the thickness of your plow blade and the mounting bracket. Standard sizes are often 1/2 inch or 5/8 inch in diameter.
Coating and Corrosion Resistance
The coating on a plow bolt plays a crucial role in its longevity, especially when exposed to moisture, salt, and debris. Common coatings include zinc plating, which offers good corrosion resistance for general use. For more aggressive environments, consider bolts with black oxide or specialized anti-corrosion coatings. Ensure the coating is uniform and free from defects to provide maximum protection.
