Description
Every farmer knows the frustration of finding bolts that have worked loose after a long day in the field. Between the constant vibration from PTO-driven implements, the jarring from hitting rocks, and the general abuse that farm equipment takes, regular nuts just don't cut it. This nylock insert locknut solves that problem by gripping the bolt threads tight so your connections stay put where they belong.
What You're Getting
- Nylon insert creates a secure lock that resists vibration loosening without thread damage
- 5/16-18 thread size fits a wide range of agricultural equipment applications
- Can be removed and reused multiple times while maintaining proper holding power
- Corrosion-resistant finish holds up to weather and chemical exposure
Built for Real Farm Work
This size locknut is commonly used throughout agricultural equipment for securing everything from implement brackets and guards to hydraulic fittings and electrical components. You'll find this thread size on cultivators, planters, mowers, balers, and loader attachments where a reliable connection is essential but you still need to be able to remove parts for maintenance.
Made to Last
The nylon insert is engineered to maintain its grip through repeated heating and cooling cycles while staying flexible enough to thread on smoothly. Unlike lock washers that can crack or jam nuts that strip threads, this design gives you consistent torque every time you install it.
Good to Know
These thread on just like a regular nut but you'll feel the resistance when the bolt enters the nylon insert—that's normal and what keeps everything tight. A little anti-seize compound on the bolt threads makes installation easier and helps prevent galling on stainless hardware.
