The Nails are an item in Homestuck. The are small, sharp objects that can be used in conjunction with the Hammer for various effects. They are first seen lying on the floor in John's room next to the Hammer. When John tries to pick them up, he accidentally knocks his Fake Arms out of his Sylladex. To make more room in his Captchalogue Deck, he combines the Nails with the Hammer. He then immediately uses them to hang the Rolled-Up Poster on the wall next to his Problem Sleuth poster.
