Description

When you’re fixing or building equipment that needs to stay together under pressure, you want fasteners you can count on. This 5/8-inch hex bolt gives you the strength and reliability to handle heavy-duty connections on everything from loader brackets to implement frames. Grade 5 steel means it’s tougher than standard bolts but won’t break the bank like Grade 8.

What You’re Getting

Grade 5 steel construction provides 120,000 PSI tensile strength for demanding applications
Zinc plating resists corrosion and gives you years of reliable service in outdoor conditions
Standard UNC threading fits right into existing holes and works with common nuts and washers
3-inch length gives you plenty of grip for thick brackets, plates, and structural connections

Built for Real Farm Work

This bolt size is perfect for medium to heavy-duty connections on tractors, implements, and shop-built equipment. You’ll find 5/8-inch bolts holding together everything from three-point hitch components to loader mounts and cultivator frames. The 3-inch length works great when you’re bolting through thick steel or need to sandwich multiple pieces together.

Made to Last

Grade 5 bolts offer the sweet spot between strength and cost—they’re about 25% stronger than Grade 2 hardware store bolts but cost less than Grade 8. The zinc coating helps them stand up to moisture and road salt, so they won’t rust out on you in a season or two.

Good to Know

Always use a flat washer 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.
