Description
When you’re fixing equipment or building something that needs to last, you need fasteners that won’t let you down. This 3/4-inch by 4-1/2-inch carriage bolt is the kind of heavy-duty hardware that holds implement frames together through seasons of hard use. The smooth, rounded head sits flush and won’t catch on anything, while the square shoulder keeps the bolt from spinning when you’re tightening the nut.
What You’re Getting
- Grade 5 strength that’s built for agricultural loads and vibration
- Zinc plating protects against rust and corrosion in outdoor conditions
- 4-1/2-inch length works great for bolting through thick steel or multiple pieces
- Square shoulder design prevents spinning during installation
- UNC thread pitch for standard nuts and compatibility
Built for Real Farm Work
This size bolt is perfect for heavy structural connections on tractors, implements, and shop-built equipment. You’ll find 3/4-inch bolts holding together three-point hitch frames, cultivator assemblies, and other equipment that takes a beating. The longer 4-1/2-inch length lets you bolt through thick material or connect multiple components in one solid joint.
Made to Last
Grade 5 steel gives you the strength you need without breaking the bank—it’s significantly stronger than hardware store bolts but costs less than premium Grade 8. The zinc coating helps it stand up to moisture, fertilizer, and road salt so it won’t rust out on you after a season or two.
Good to Know
Always use a washer under the nut to distribute the load properly and prevent pull-through on thinner materials. If you’re replacing old rusted bolts, clean the threads with a tap first. A dab of anti-seize compound makes future removal much easier, especially if the connection might see heat or chemicals.
