Abstract

PURPOSE:To make mounting of blind plugs through automatic remote operation with small force possible by using the plugs each having a hole for mounting a tool on the rear end side of the body and mounted with plural plate-like fins engraved with spiral grooves on the surface on the leading end side. CONSTITUTION:A hole 3 for mounting a tool of a hexagonal shape in section is opened in the rear end part of a blind plug body 2 in order to transmit rotating force. A bolt 4 is projected to the leading end of the body 2. Plural plate-like fins 5 having spring elasticity are disposed annularly by leaving clearances 6 respectively, and are fixed to the plug body 2 by means of a nut 8 screwed to the bolt 4. The fins 5 are bulged to the size slightly larger than that in the leading end part of the body 2 and tapers 9 are formed to the leading ends of the fins 5, in connection to which spiral grooves 10 are formed on the surface of the fins 5. When the plug 1 is forced into a tube while it is rotated by a tool inserted into the hole 3, it is mounted into the hole.
