    Abstract: The present invention pertains to an assemblage of sealing nail essentially containing a nail, a propeller, and a blocker that is partially extended beyond the propeller. Wherein, the nail would sequentially penetrate the propeller, the blocker, and then a plank. By means of the nail entering the plank, the propeller and the blocker would be simultaneously urged to densely cover up where the nail inserted. Therefore, a preferred sealing efficiency between the nail and the plank is achieved to guarantee a favorable grouting on the plank.
