Claims3
A device for inhibiting the corrosion of a nut and the exposed portion of a threaded shaft extending beyond said nut when said nut is threaded onto said threaded shaft, comprising:
- a. a protector cap, having a first end, a second end, and a solid side wall connecting said first end and said second end, and wherein said first end contains an opening leading into a hollow interior bounded by said solid side wall and said second end, and wherein said opening is sized to slip over and fictionally engage said nut, thereby holding said protector cap in place over said nut and said exposed portion of said threaded shaft;
- and
- b. a highly viscous, corrosion-inhibiting liquid, placed within said hollow interior so as to coat and protect said nut and said exposed portion of said threaded shaft.
