Exhaust Nut — 3/8"-16 Hex, Replacement Hardware for Exhaust Clamps & Flanges SKU: QT41557

This exhaust nut replaces worn or missing hardware so pipe joints, clamps, and flanges stay tight and leak-free. It’s a simple fix that helps stop rattles, soot streaks, and loose connections in the exhaust run.

Built for daily farm use, the hex profile provides positive wrenching and holds torque through vibration and heat cycles, supporting a reliable seal at brackets, boxes, and pipe-to-pipe joints.

• Size and thread: 3/8"-16 coarse for common exhaust hardware
• Hex design for secure tool engagement and repeatable torque
• Clean, consistent threads for smooth assembly
• Corrosion-resistant finish suited to heat, moisture, and road grime

Installation Tip: Allow the system to cool, clean the bolt or stud threads, apply a light coat of anti-seize, then tighten hardware evenly in stages; recheck torque after the first heat cycle.

A practical piece of hardware that helps keep your exhaust secured and your machine working the way it should.
