SKU: SMA-120-P58X312 Heavy-Duty Plow Bolt for Agricultural Implements and Field Cultivators

When you're working cultivator points, plow shares, or other implement attachments, you need bolts that can handle the job. These Grade 5 plow bolts are built tough to stand up to the rocks, roots, and hard-packed soil that regular hardware store bolts just can't handle. The zinc coating keeps rust at bay season after season.

What You're Getting

• Grade 5 strength—stronger than standard bolts but won't break like brittle Grade 8 in shock loads
• 5/8 inch diameter provides solid holding power for heavy attachments
• 3-1/2 inch length works for most standard implement mounting applications
• Zinc finish resists corrosion even when exposed to fertilizer and field moisture
• UNC threads for reliable fit with standard agricultural nuts and hardware

Built for Real Farm Work

These plow bolts are the go-to choice for mounting cultivator points, plow shares, disc blades, and other ground-engaging tools on field cultivators, plows, and tillage equipment. They're commonly used on implements from Glencoe, Kewanee, White, Taylor, Krause and many other manufacturers. Whether you're working corn stubble in the fall or preparing seedbeds in the spring, this is the hardware that keeps your points and blades secure.

Made to Last

Farm implements take a beating, and regular bolts just don't cut it when you're hitting rocks or pushing through tough ground. The Grade 5 steel gives you the strength you need without being so hard it snaps under sudden impact loads. The zinc plating holds up to the chemicals and moisture that come with farm work.

Good to Know

Always replace plow bolts in pairs to maintain even wear patterns on your implements. When installing, use a thread locker on the nut if you're working in sandy or abrasive conditions—it'll keep things tight longer. Check bolt torque after the first few hours of field work, as new installations tend to settle in.
