A grommet is formed with elastomeric portions and relatively rigid portions by multi-shot core injection molding. The grommet. includes a head and a shank. The head includes a central planar area of the relatively rigid material, such as nylon. The head further includes a lower layer of elastomeric material, facing the shank, which serves as a seal or washer. The head further includes an upper layer of elastomeric material which includes countersunk portions around the blind aperture which is formed in the head and extends through a portion of the shank. The shank includes a rounded nose formed on a distal portion and has elastomeric material formed on an exterior thereof.

[ What is claimed is:] [1.]1. A grommet comprised of an elastomeric material and a relatively rigid material integrally bonded thereto, the grommet comprising:a relatively planar head with a first side and a second side;a shank including a proximal end and a distal end, said proximal end extending from said second side of said planar head;an aperture with a mouth formed on said planar head, said aperture extending into said shank;said planar head comprising a first layer of the relatively rigid material and a second layer of the elastomeric material, said second layer formed on said second side; andsaid proximal end of said shank including exposed surfaces of the relatively rigid material and said distal end of said shank including an integral tip formed of the elastomeric material surrounding and sealing said aperture.
