Description
There’s nothing worse than having nuts work loose on your equipment right when you need it most. Whether you’re bouncing across a rough field or running your PTO at full tilt, vibration is constantly trying to back out your fasteners. This 5/8 inch nylon lock nut puts an end to that worry with a built-in nylon collar that grips tight and stays put.
What You’re Getting
- Nylon insert creates friction against threads to prevent loosening under vibration
- Zinc plating protects against rust and corrosion in wet field conditions
- Grade 2 steel provides reliable strength for general farm applications
- UNC coarse threads make installation quick and easy with standard tools
Built for Real Farm Work
This lock nut is sized perfectly for the 5/8 inch bolts you’ll find all over your tractor and implements. It’s the go-to choice for securing hydraulic fittings, PTO guards, loader attachments, and cultivator shanks where vibration tries to shake things loose. The coarse UNC threads thread on fast and grip well in the softer metals you often work with on farm equipment.
Made to Last
The zinc coating gives you solid protection against the moisture and chemicals that come with farm work. The nylon insert is designed to compress just enough to lock tight without stripping out when you need to remove it later for maintenance.
Good to Know
You’ll feel more resistance when threading this on compared to a regular nut—that’s the nylon doing its job. Tighten to standard torque specs for the bolt grade you’re using. The nylon insert can be reused several times, but keep a few spares handy for critical applications where you can’t afford a failure.
