A plug for repairing steel belted tires includes an insert member having a shank containing threads and joined to an uppermost wedge element provided with a tool engaging recess. A resilient shroud encases the majority of the insert member and includes external threads on its lower portion whereupon the shank threads interlock the insert and shroud such that as the insert is screwed into a tire puncture, the shroud is simultaneously screwed into the tire and insures an enhanced securing and sealing action.
