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.
