Description

When you’re mounting moldboards, securing cultivator shanks, or replacing worn hardware on tillage equipment, you need bolts that can handle the stress. Grade 5 bolts offer the sweet spot between strength and cost—they’re about 25% stronger than Grade 2 hardware store bolts but cost less than Grade 8. The zinc coating helps them stand up to moisture and road salt, so they won’t rust out on you in a season or two. This No. 3 plow bolt is specifically designed for the demanding conditions of farm work.

What You’re Getting

Grade 5 strength that’s built for the real world—stronger than hardware store bolts but not overkill for most farm applications
Zinc plating that fights off rust and corrosion from field moisture and road chemicals
UNC (coarse) threads that go together easier in dirty conditions and resist cross-threading
1-1/4 inch length that’s perfect for standard plow and tillage tool mounting

Built for Real Farm Work

This is a true plow bolt, meaning it’s designed specifically for attaching shares, moldboards, and other tillage components that take a beating in rocky or tough soil conditions. The 1/2-inch diameter gives you plenty of strength for medium-duty connections without being oversized for the job. You’ll find this size used throughout tillage equipment from compact tractor implements to mid-size field cultivators.

Made to Last

The zinc coating helps them stand up to moisture and road salt, so they won’t rust out on you in a season or two. Grade 5 steel provides the right balance of strength and toughness for agricultural use—hard enough to resist bending under load but not so brittle that it’ll snap if you hit a rock.

Installation Notes

Always use a flat washer under the head and nut to distribute the load properly. If you’re replacing rusted bolts, clean out the threads with a tap if needed. A little anti-seize compound on the threads makes future removal much easier, especially if the connection might see heat or road salt.
