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.
Frequently Asked Questions
What is the difference between plow bolts and standard bolts?
Plow bolts are specifically designed for attaching plow blades, often featuring a square or ribbed neck to prevent rotation and a countersunk head to sit flush. Standard bolts may have different head styles and neck designs not optimized for the shear and impact forces experienced by plows.
How do I determine the correct size plow bolt?
Measure the thickness of your plow blade and the mounting bracket where the bolt will pass through. Add these measurements together to determine the minimum bolt length required. The diameter should match the pre-drilled holes in your equipment, typically 1/2 inch or 5/8 inch.
Are stainless steel plow bolts worth the extra cost?
Stainless steel plow bolts offer superior rust and corrosion resistance, making them ideal for use in wet or salty environments. While they may be more expensive, their longevity and reduced maintenance can justify the cost for frequent or demanding applications.
What does the grade of a steel plow bolt signify?
The grade of a steel bolt, such as Grade 5 or Grade 8, indicates its tensile strength and hardness. Higher grades mean the bolt can withstand greater stress before breaking, making them more suitable for heavy-duty plowing applications where significant force is applied.
