Tuff Nut Breaker

Product Description

Tuff Nut Breaker is a heavy-duty penetrant that breaks down rust and corrosion to help you break loose seized parts and mechanisms. Bust the rust, not your knuckles!


Heavy Duty Rust Buster. Tuff Nut Breaker contains strong penetrating qualities that break through the rust and loosen seized mechanisms.

Breaks Down Corrosion. Tuff Nut Breaker dissolves corrosion and conditions the metal surfaces, combating future corrosion build-up.

Fine Lubricant for Delicate Mechanisms. Tuff Nut Breaker is formulated with AFMT, which combined with its powerful penetrating qualities, allow it to reach tight spaces and leave behind a super lubrication barrier.

Saves Working Time. Tuff Nut Breaker’s unique ability to break down rust and corrosion faster enables you to spend less time battling seized parts and more time getting the job done.


Spray generously on the desired area prior to working on it. Can also be reapplied every maintenance period to prevent corrosion. Tuff Nut Breaker retains its effectiveness from -30°C (-22°F) to 200°C (392°F).
