Description

If you’ve ever tried to tighten a regular hex bolt through wood or in a spot where you can’t get a wrench on both ends, you know why carriage bolts exist. The square shoulder sits flush in wood or square holes and keeps the bolt from spinning while you tighten the nut from the other side—no more wrestling with two wrenches in tight spots.

What You’re Getting

  • Grade 5 strength that’s 25% stronger than hardware store bolts but won’t break the budget
  • Zinc plating protects against rust and corrosion from field moisture and weather
  • Square shoulder design prevents spinning during installation and removal
  • 1-1/4 inch length gives you good thread engagement without excess sticking out
  • Standard UNC thread pitch works with common nuts and washers

Built for Real Farm Work

This size bolt is perfect for mounting brackets, securing implement guards, attaching wood components to metal frames, and general repair work around the shop. You’ll find these handy for everything from gate hardware to equipment modifications where you need a clean, flush appearance on one side.

Made to Last

The zinc coating 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 plenty of strength for most farm applications without the cost of Grade 8 hardware.

Good to Know

Always use a flat washer under the nut to distribute the load properly and prevent the nut from pulling through softer materials. If you’re going through metal, make sure your hole is square or drill it round and let the shoulder bite in as you tighten.
