Description

When you’re working on equipment that takes a beating, you need fasteners that won’t let you down. These 7/16-inch hex bolts are the workhorses of the farm shop—strong enough for serious connections but priced right for bulk repairs and maintenance work. Whether you’re fixing a broken bracket or building something from scratch, these bolts give you the reliability you need.

What You’re Getting

  • Grade 5 steel construction that’s 25% stronger than hardware store bolts
  • Zinc plating protects against rust and corrosion for longer life
  • 3-1/2 inch length handles thick connections and multiple pieces
  • Pack of 25 keeps you stocked for ongoing projects and repairs
  • Standard coarse thread (#3 UNC) fits common nuts and threaded holes

Built for Real Farm Work

These 7/16-inch bolts are perfect for medium-duty connections on tractors, implements, and shop projects. You’ll use them for everything from repair brackets to hitch components, loader attachments, and cultivator frames. The 3-1/2 inch length gives you plenty of thread engagement when bolting through thick steel or sandwiching multiple pieces together.

Made to Last

Grade 5 steel hits the sweet spot between strength and cost—tougher than standard bolts but more affordable than Grade 8. The zinc coating helps them stand up to moisture and road salt, so they won’t rust out on you after a season or two of field work.

Good to Know

Always use flat washers 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.
