Description
When you’re working on your disc harrow and need to secure those heavy disc blades and axle assemblies, you don’t want to mess around with inferior hardware. This 1-1/8 inch hex nut is built for the serious torque and constant vibration that comes with tillage equipment. Whether you’re replacing worn hardware or building up a new axle setup, this zinc-plated nut gives you the holding power you need for field work.
What You’re Getting
- Heavy-duty Grade 2 construction that handles the stress of disc harrow operation
- Zinc plating protects against rust and corrosion, even in muddy field conditions
- Standard hex design works with your existing tools and sockets
- Precise threading ensures a tight, secure fit every time
Built for Real Farm Work
This size nut is commonly used on 1-1/8 inch square axles found throughout disc harrow equipment. You’ll find this size on everything from smaller utility disc harrows to heavy-duty tillage rigs. It’s the workhorse fastener that keeps disc blades, spacers, and bearing assemblies locked in place while you’re working the ground.
Made to Last
The zinc coating isn’t just for looks—it’s your protection against the elements. Field work means exposure to moisture, soil acids, and temperature swings that can eat up regular hardware. This coating gives you the corrosion resistance to keep these nuts doing their job season after season.
Installation Notes
Use a proper torque wrench when tightening to avoid over-stressing the threads. A little anti-seize compound on the threads makes future removal much easier, especially if you’re working in wet or muddy conditions. Keep a few extras on hand—there’s nothing worse than being stuck in the field with stripped threads.
