Description
If you’ve ever had a plow bolt head wear through or break off when you’re trying to get through tough ground or rocky soil, you know how frustrating it can be. This special No. 3 plow bolt comes with an oversize head that gives you more bearing surface and better holding power than standard bolts. When you’re mounting cultivator sweeps and shovels that take a beating, this extra head size makes all the difference.
What You’re Getting
- Oversize head provides more surface area for better load distribution and longer wear
- Grade 5 UNC threading gives you the strength to handle heavy tillage conditions
- Zinc chromate plating resists rust and corrosion from moisture and chemicals
- Special design specifically engineered for cultivator sweeps and ground-engaging tools
Built for Real Farm Work
This bolt is made for the tough jobs—mounting cultivator sweeps, shovels, and other tillage tools that dig into hard ground day after day. The oversize head spreads the load better than regular bolts, so you’re less likely to have bolt heads wear through the metal or cause stress cracks around the mounting holes.
Made to Last
The zinc chromate plating isn’t just for looks—it provides excellent protection against the moisture, fertilizers, and soil chemicals that eat up ordinary hardware. Grade 5 strength means this bolt can handle the shock loads and vibration that come with ground engagement without stretching or breaking.
Good to Know
These bolts are sold in multiples of 100, which makes sense since you’ll typically need several for each sweep replacement. Keep a few extra on hand—there’s nothing worse than having one bolt fail when you’re trying to get a field finished. The oversize head may require slightly larger washers if you’re used to standard plow bolts.
