Description

You know how standard nuts have a way of working loose just when you least expect it? That’s where these nylon lock nuts come in handy. The nylon insert grabs onto the threads and won’t let go, even when your tractor’s bouncing across rough ground or your implement’s vibrating like crazy. It’s the kind of simple upgrade that saves you from crawling under equipment to retighten bolts every few weeks.

What You’re Getting

Nylon insert that locks tight but still comes off when you need it to
Zinc coating that fights off rust and corrosion season after season
Grade 2 construction that’s tough enough for everyday farm use
Standard UNC threads that work with any 5/16 inch bolt you’ve got
Self-locking design that stops vibration from loosening your connections

Built for Real Farm Work

These nuts are perfect for securing guards, brackets, and smaller components on all kinds of agricultural equipment. Whether you’re mounting implements on your three-point hitch, securing hydraulic lines, or bolting down access panels, the 5/16 inch size handles a lot of the everyday fastening jobs around the farm.

Made to Last

The zinc plating keeps these nuts looking good and working right, even when they’re exposed to moisture, fertilizer, and all the other harsh conditions that come with farm life. The nylon insert stays flexible through hot summers and cold winters, giving you reliable locking power for years.

Good to Know

These nuts will feel snug when you thread them on—that’s the nylon doing its job. Use a wrench to get proper torque, but don’t over-tighten or you might damage the nylon insert. They can be removed and reused, though the locking power works best the first few times.
