Description

When you’re fixing implements or maintaining your tractor, having the right hardware makes all the difference. This 1-1/2 inch hex nut gives you a secure connection that won’t back out under the vibration and stress of field work. Whether you’re replacing a worn nut or completing a repair, this Grade 2 zinc-plated fastener delivers the reliability you need to keep working.

What You’re Getting

Grade 2 steel construction that handles the loads agricultural equipment puts on hardware
Zinc plating provides excellent corrosion resistance against moisture and road salt
UNF (Unified National Fine) thread pitch for precise fit and strong holding power
Standard hex profile works with any 1-1/2 inch wrench or socket

Built for Real Farm Work

This nut is sized for heavy-duty applications where you need serious clamping force. You’ll find these on implement hitches, cultivator shanks, disk harrow assemblies, and other spots where vibration and heavy loads demand a nut that stays put. The fine thread pitch gives you better holding power than coarse threads in critical connections.

Made to Last

The zinc plating isn’t just for looks—it forms a protective barrier that keeps rust at bay even when you’re working in wet conditions or storing equipment outside. Grade 2 steel provides the strength needed for most farm applications without being overkill for everyday repairs.

Good to Know

This nut replaces Domries part number 4N-150. The UNF thread means you’ll get more threads per inch than standard coarse thread nuts, which translates to better holding power and less chance of loosening over time. Always check your bolt thread pitch before ordering to make sure you get the right match.
