💡 How do serrated flange nuts prevent exhaust leaks better than round ones?
Serrated surfaces bite into metal and hold tight when vibrations shake loose around your pipe joints. Here is why swapping to this setup stays handy during repairs.
- Knurled edges clamp down firmly without needing extra thread locker
- Flat contact area distributes force evenly across warped manifold lips
- Self locking design handles rapid temperature swings without backing off
- Saves time on the shop floor compared to cutting and chipping old bolts away
