SKU: SMA-120-84218 Hex Nut 1-1/8 Inch Zinc Plated Grade 2 with Fine Thread

When you're working on the heavy-duty components of your tractor or implement, you need hardware that's built to handle serious loads. This 1-1/8 inch hex nut is sized for the bigger bolts that hold together the parts that matter most—hydraulic cylinders, loader arms, three-point hitches, and other high-stress components where a loose fastener isn't just inconvenient, it's dangerous.

What You're Getting

• Grade 2 steel construction that provides reliable strength without being brittle
• Zinc plating protects against rust and corrosion from weather and hydraulic fluids
• Fine UNF thread pitch gives you more threads per inch for stronger holding power
• 1-1/8 inch size fits the heavy-duty bolts used in critical agricultural applications
• Standard hex design works with any socket or wrench set you've got

Built for Real Farm Work

Agricultural machinery and equipment subject to constant vibration require reliable fastening solutions that maintain secure connections throughout demanding operations, essential for securing implement attachments, hydraulic components, PTO assemblies, and structural connections on tractors, combines, and farming equipment. The large 1-1/8 inch size is commonly found on loader pivot points, three-point hitch pins, and heavy implement mounting brackets.

Made to Last

The zinc coating on this nut helps it stand up to the moisture, chemicals, and temperature swings that come with farm life. The zinc plating extends service life by protecting against rust and corrosion, while the fine UNF thread provides stronger holding power than coarse threads in critical applications.

Good to Know

Fine threads like these UNF threads require a bit more care during installation—they're less forgiving of cross-threading than coarse threads. Take your time getting the nut started straight, and you'll appreciate the extra holding power when the job's done. Always pair with the correct grade bolt for your application.
