SKU: SMA-120-P38X2 Zinc Plated Plow Bolt 3/8 Inch X 2 Inch Grade 5 for Agricultural Tillage Equipment

When you're swapping out worn plow points, replacing cultivator shovels, or mounting any tillage attachment, you need bolts that can handle the dirt, rocks, and constant vibration that comes with working the soil. This 3/8 inch plow bolt is specifically designed for mounting cultivator points and other tillage components where a standard hex bolt just won't cut it. The countersunk head sits flush against your implement while the zinc coating keeps rust at bay season after season.

What You're Getting

• Grade 5 strength that holds up under heavy field loads and impact stress
• Zinc plating provides excellent corrosion resistance against moisture, fertilizers, and soil chemicals
• 2-inch length is perfect for mounting points, shovels, and other medium-thickness attachments
• UNC thread pitch ensures compatibility with standard agricultural nuts and hardware
• Countersunk head design allows for flush mounting and reduces snagging on crop residue

Built for Real Farm Work

This bolt is commonly used on field cultivators from manufacturers like Glencoe, Kewanee, White, Taylor, and Krause, where it secures everything from spring-loaded cultivator points to rigid field finishing attachments. You'll find this same bolt holding together disc harrows, field cultivators, and chisel plows that work thousands of acres every season.

Made to Last

The Grade 5 rating means this bolt is stronger than your typical hardware store variety and can handle the shock loads that come with hitting rocks or working through tough ground. The zinc coating isn't just for looks—it forms a protective barrier that stands up to years of exposure to soil acids, fertilizer salts, and morning dew without the rust-out you'd see with plain steel.

Good to Know

These are direct replacements for most OEM plow bolts in this size. Keep a few extras in your toolbox since they're easy to lose in the field during repairs. When installing, hand-start the threads to avoid cross-threading, then snug down with a socket or box-end wrench—no need to overtighten since the Grade 5 steel does the heavy lifting.
