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
The fine UNF thread pattern provides stronger holding power than coarse threads, making it ideal for applications where vibration and dynamic loading could cause standard fasteners to fail. The zinc yellow coating adds an extra layer of protection against the elements, so these bolts keep doing their job season after season.
Good to Know
UNF threads are finer than standard threads, so they thread in slower but hold tighter. If you’re replacing an existing bolt, make sure it’s also UNF—they’re not interchangeable with coarse thread bolts. A little anti-seize compound on the threads makes future removal easier and prevents galling.
