WD-40 Industrial Strength Fast-Acting Specialist Penetrant for Metal, Locks and Nuts, 2.75 oz.

WD-40 Specialist Penetrant penetrates hard-to-reach crevices, threads and seams to free stuck, frozen or seized equipment and parts. The low-odor, fast-acting formula penetrates up to 2x faster than the competition* with capillary action that removes rust and corrosion on threads, locks, chains, nuts and bolts, while leaving behind a protective layer that prevents rust from re-forming. This industrial-strength penetrant works on contact and comes with a permanently attached smart straw that sprays two ways for broad coverage or a more precise application. Whether you're working with metal, rubber or plastic, this heavy-duty penetrant can tackle all of your tough jobs with ease. *Test Lab: Fred Cuneo (3rd Party); Nail Climb Test; Test date: 03/2021.
