Description

When you’re working on equipment repairs or building custom fixtures around the farm, sometimes you need a bolt that’s got the strength to handle the job but won’t back out when things get rough. This 5/8 inch carriage bolt with its smooth, rounded head and square shoulder is designed to stay put once it’s tightened down, making it perfect for securing brackets, guards, and heavy-duty hardware.

What You’re Getting

  • Grade 5 steel construction handles the stress and vibration of farm equipment
  • Zinc plating resists corrosion from moisture, fertilizers, and chemicals
  • Square shoulder design locks into place to prevent spinning during installation
  • 3-1/2 inch length gives you plenty of thread engagement for secure connections
  • UNC thread pitch works with standard nuts and washers you’ve got on hand

Built for Real Farm Work

This carriage bolt is handy for all kinds of projects around the farm—mounting PTO shields on tractors, securing implement brackets, building feed bunks, or fixing gates and panels. The 5/8 inch diameter gives you the strength for heavy-duty applications while the zinc finish helps it hold up to weather and chemicals you’ll encounter in agricultural work.

Made to Last

The zinc plating isn’t just for looks—it forms a protective barrier that keeps rust and corrosion at bay, even when you’re working in wet conditions or around fertilizers and spray chemicals. Grade 5 steel provides the tensile strength you need for applications where failure isn’t an option.

Good to Know

The square shoulder under the head means you won’t need to hold the bolt with a wrench while tightening the nut—just drill a square hole or let the shoulder bite into softer materials like wood. For metal applications, a round hole works fine since the square shoulder will grab and prevent spinning as soon as you start applying torque.
