Description

There’s nothing more frustrating than having a bolt back out just when you need your equipment working. Whether you’re dealing with vibration from running implements or the constant shake of field work, a regular nut just won’t stay put like it should. That’s where this nylon lock nut comes in—it grips tight and stays that way, so you can focus on farming instead of chasing loose bolts.

What You’re Getting

Nylon insert that creates a secure, vibration-resistant connection that won’t back out
Zinc plating protects against rust and corrosion for seasons of reliable service
Grade 2 construction handles the stress of agricultural applications without breaking
UNF (fine) thread pitch provides better holding power in critical connections

Built for Real Farm Work

This lock nut is sized for 7/16 inch bolts and is perfect for securing implement attachments, hydraulic fittings, PTO assemblies, and structural connections on tractors and equipment. Whether you’re mounting a cultivator, fixing a loader arm, or tightening up any connection that takes a beating in the field, this nut does the job right.

Made to Last

The zinc coating keeps rust at bay, even when you’re working in wet conditions or storing equipment outside. The nylon insert is tough enough to handle repeated installations while still providing that secure grip you need. It’s built to farm standards, not hardware store quality.

Good to Know

You’ll feel the nylon insert engage as you thread it on—that resistance is normal and exactly what keeps everything tight. Follow your regular torque specs for the bolt size and don’t over-tighten, which can damage the insert. This is a direct replacement that threads on just like any standard nut, but stays put like it should.
