Description

When you’re putting together heavy equipment or doing repairs on your tractor, you need fasteners that can handle the job without letting you down. This 5/8-inch by 5-inch UNF hex bolt gives you the strength and reliability for medium to heavy-duty connections where regular hardware store bolts just won’t cut it.

What You’re Getting

Fine UNF thread pattern that holds tight under vibration and heavy loads
Zinc and yellow plating protects against rust and corrosion in outdoor conditions
5-inch length perfect for through-bolting thick steel or connecting multiple pieces
5/8-inch diameter provides solid strength for demanding agricultural applications

Built for Real Farm Work

This bolt size is your go-to for securing three-point hitch components, loader mounts, cultivator frames, and other implement connections. The 5-inch length works great when you’re bolting through thick steel plates or need to sandwich brackets and spacers together. You’ll find this size holding together everything from hay equipment to shop-built modifications.

Made to Last

The fine UNF threads give you stronger holding power than coarse threads, which matters when your equipment takes a beating in the field. The zinc and yellow coating helps these bolts stand up to moisture, fertilizer splash, and road salt so they won’t rust out on you after a season or two of hard use.

Installation Notes

Always use flat washers under the head and nut to spread the load properly. If you’re replacing old rusted bolts, clean the threads with a tap first. A dab of anti-seize on the threads makes future removal much easier, especially if the connection might see heat or chemical exposure.
