Description

When you need a bolt that can handle the heavy lifting on your tractor or implement, this 3/4-inch hex bolt delivers the strength you’re looking for. The fine UNF threads and substantial 3-1/2-inch length make it perfect for bolting through thick steel plates or securing heavy components that need to stay put through seasons of hard work.

What You’re Getting

  • Fine UNF thread pattern provides stronger holding power than coarse threads, especially important for vibrating equipment
  • Zinc and yellow coating protects against rust and corrosion, even in wet field conditions
  • 3-1/2-inch length works great for through-bolting thick materials or sandwiching multiple pieces
  • Heavy-duty 3/4-inch diameter handles serious loads without stretching or breaking

Built for Real Farm Work

This bolt size is ideal for securing implement frames, loader attachments, three-point hitch components, and other heavy-duty connections on tractors and farm equipment. Whether you’re mounting a cultivator, assembling structural frameworks, or connecting axle components, this bolt provides the strength needed for agricultural applications.

Made to Last

The zinc and yellow plating system gives you superior corrosion protection compared to plain steel bolts. This coating helps the bolt stand up to moisture, road salt, and the harsh conditions that come with outdoor farm work, so you won’t be replacing rusted hardware every season.

Good to Know

Always use flat washers under both the head and nut to distribute the load properly across the material. If you’re replacing old rusted bolts, clean out the threaded holes with a tap first. A dab of anti-seize compound on the threads makes future removal much easier, especially if the connection might see heat or get exposed to road salt.
