Description
When you're tightening down linkage pins, securing implement brackets, or making adjustments on three-point equipment, regular nuts can back off from vibration and leave you with loose connections. That's where this 3/8-16 half jam nut earns its keep. It's thinner than a regular nut, so you can snug it down against another nut or component to lock everything in place tight.
What You're Getting
- 3/8-16 UNC thread fits standard bolts and studs on most farm equipment
- Half-height design allows for dual-nut locking without taking up excessive thread length
- Quality steel construction handles the stress of field vibration and temperature changes
- Works as a lock nut when paired with regular nuts or threaded against shoulders
Built for Real Farm Work
This jam nut works on everything from three-point hitch adjustments to implement mounting hardware. You'll find it handy on cultivator shanks, disc gang assemblies, planter row units, and anywhere you need to prevent nuts from backing off during operation. It's the kind of small part that prevents big headaches when you're trying to get fieldwork done.
Made to Last
Farm equipment shakes, rattles, and vibrates constantly, which is exactly why jam nuts exist. This one's built from quality steel that won't strip out or crack under normal use. The threads are cut clean and true, so it'll thread on smoothly and stay put once you tighten it down.
Good to Know
Thread this jam nut on first, then your regular nut on top. Tighten the regular nut to spec, then back the jam nut up against it and snug it down. The two nuts wedged against each other prevent either one from loosening. Keep a few extras in your toolbox - once you start using jam nuts, you'll find more places where they come in handy.
