Description
When you’re dealing with exhaust leaks on your Massey Ferguson, those little brass nuts holding your manifold together might seem insignificant—but they’re actually doing a pretty important job. These 3/8″ UNF brass nuts secure your exhaust manifold to the engine, keeping everything sealed tight so exhaust gases go where they’re supposed to instead of leaking into your cab or around the engine bay.
What You’re Getting
- Proper 3/8″ UNF thread pitch that matches your original Massey Ferguson hardware
- Brass construction that resists corrosion and handles the constant heating and cooling cycles
- Heat-resistant material that won’t seize up like steel nuts often do on exhaust systems
- Sold in a pack of 10 so you’ll have extras for future repairs or other manifold work
Built for Real Farm Work
These nuts are designed for the classic Massey Ferguson tractors that are the backbone of many farming operations—from the compact utility models up through the mid-size workhorses. Whether you’re running a loader, bush hogging, or doing field work, a properly sealed exhaust system keeps fumes out of your workspace and maintains proper engine performance.
Made to Last
Brass might cost a bit more than steel, but there’s a good reason exhaust hardware uses it. The constant heating and cooling from your engine’s exhaust system would cause steel nuts to corrode and seize. These brass nuts thread on and off easily even after years of service, which you’ll appreciate when it’s time for future repairs or maintenance.
Good to Know
Before installing new nuts, clean the threads on both the nut and stud with a wire brush to remove any corrosion or old thread locker. A light coat of anti-seize compound on the threads helps prevent future problems. Don’t over-tighten—brass is softer than steel and the threads can strip if you get too aggressive with the wrench.
