ABSTRACT:
An improved impact plug assembly is provided which will not become entangled with neighboring such assemblies when a plurality thereof is shipped or stored in containers prior to use to close apertures in a workpiece. The plug is of the type having a cooperating crossbar for locking the plug in place in the aperture to be closed, the crossbar being retained in diametrically opposed slots formed in the peripheral walls of said plug. The improvement comprises the provision of raised means such as dimples on the surface of the plug on each side of the crossbars to prevent projecting edges of crossbars of neighboring plugs in a storage bin from becoming inextricably entangled.
