Description

When you’re bolting together implement brackets, cab mounts, or any equipment where you need a smooth finish on one side, carriage bolts are the way to go. The square neck locks into place so the bolt won’t spin when you’re tightening the nut from the other side—no need to hold it with another wrench. This 1/2-inch by 1-inch size handles light to medium-duty connections where you need things secure but not overpowering.

What You’re Getting

  • Grade 5 strength that’s 25% stronger than hardware store bolts but costs less than Grade 8
  • Zinc coating protects against rust and corrosion so bolts won’t seize up over time
  • Square neck design prevents spinning during installation—just tighten from the nut side
  • Smooth, rounded head provides a clean appearance on the visible side
  • UNC thread pitch for standard compatibility with most nuts and threaded components

Built for Real Farm Work

This size works great for mounting brackets, securing panels, and assembling lighter implement components. You’ll find these handy for everything from toolbox mounts to guard brackets, hydraulic reservoir supports, and shop-built equipment where appearance matters on one side.

Made to Last

The zinc plating helps these bolts stand up to moisture and road salt, so they won’t rust out on you in a season or two. Grade 5 gives you the sweet spot between strength and cost—tough enough for most farm applications without breaking the budget.

Good to Know

Always use a flat washer under the nut to distribute the load properly. The square neck needs to seat fully in the hole or bracket slot to prevent spinning. If you’re replacing old rusty hardware, a little anti-seize compound on the threads makes future removal much easier.
