Penetrating oil is an extremely low-viscosity oil that can penetrate into the area between threads on a fastener. A stuck fastener is often heated, sprayed with penetrating oil, and then tapped with a hammer. | Penetrating oil is an extremely low-viscosity oil that can penetrate into the area between threads on a fastener.

| + | Some comments on penetrating oils. WD-40 is not a penetrating oil, it is a corrosion preventative. There is problem with the idea that penetrating oils can penetrate rusted together parts. I have done some testing. For a whole week I put Kroil on a head studs. I than pulled one stud from the head that felt like it wanted to come. As I suspected, it was dry. If the bolt is free enough for penetrating oil to seap through then it will come out without any oil. | ||
