Built for Real Farm Work
This nut works across a wide range of agricultural applications where 3/8 inch fasteners are common. You’ll find this thread size on everything from cultivator points and toolbar attachments to hydraulic fittings and PTO guards. It’s the go-to size for medium-duty connections that need to stay tight but aren’t carrying the heaviest loads.
Made to Last
Farm equipment fasteners take a beating from constant vibration, temperature swings, and exposure to moisture, chemicals, and debris. This hex hi-nut is built to handle those conditions without backing off or corroding. The additional thread engagement of the hi-nut design means better holding power when your equipment is working hard.

The hex design makes removal and installation straightforward with standard wrenches or sockets. Keep a few extras on hand since 3/8 inch is such a common size in agricultural applications. When reassembling components, run the nut on by hand first to avoid cross-threading, then tighten to your equipment’s specified torque.
