A fastening device having a pin with an enlarged head and a central longitudinal bore to receive a rod having a head with a drive receiving recess and a footed keeper. The pin and rod have adjacent surfaces that aid in the prevention of turning relative to each other. In use, the pin, with the footed keeper in alignment, is inserted to aligned openings in overlapping maps used in roadways and a tool is used to turn the keeper a quarter turn to prevent the pin from coming out of the opening and securing the mat.
