Description
When you’re building or fixing equipment that absolutely has to hold together under serious stress, this isn’t the time for lightweight hardware store bolts. This 5/8″ x 7″ UNF hex bolt is built for the heavy-duty connections where a failure means downtime, expensive repairs, or worse. The fine UNF threads and zinc yellow plating make it the go-to choice for farmers who need fasteners they can trust.
What You’re Getting
- Extra-long 7-inch length handles thick structural assemblies and through-bolting jobs
- Fine UNF threads provide stronger holding power than coarse threads—critical for vibration resistance
- Zinc yellow plating fights off rust and corrosion better than standard zinc coating
- Heavy-duty construction handles the extreme loads typical of modern farm equipment
- 15/16″ hex head gives you plenty of grip for high-torque applications
Built for Real Farm Work
This bolt shines when you’re working on the heavy stuff—three-point hitch assemblies, loader mounts, cultivator frames, and combine components that see serious stress. The 7-inch length is perfect for bolting through thick steel plates or when you need to sandwich multiple pieces together. You’ll find this size holding together everything from axle assemblies to structural framework on the biggest farm equipment.
Made to Last
The fine thread design isn’t just about holding power—it also resists loosening from vibration and shock loads that would cause standard fasteners to fail. The zinc yellow plating system provides superior protection against the fertilizers, moisture, and chemicals that eat up ordinary bolts. This is the same quality you’d find on OEM equipment.
Installation Notes
Take your time threading this one in—fine threads require careful alignment to prevent cross-threading. Always use the proper torque specs for your application, and make sure you’ve got adequate clearance for the full 7-inch length. A drop of anti-seize compound on the threads isn’t a bad idea for future removal.
