ABSTRACT:
An apparatus for positioning of fasteners normal to a surface through which the fasteners are to be inserted is described. The apparatus includes a sheet of material comprising a plurality of holes therethrough, where the holes are positioned to correspond with bores through the surface through which the fasteners are to be inserted, and a plurality of grommets. The grommets are operable for mounting in the holes in said sheet. Each grommet includes a hole centered therein and sized such that the grommet will support a fastener placed therein, and a plurality of radial keyways extending from the centered hole, the keyways having a specific radial depth to provide finger tabs at the centered hole to maintain support of the corresponding fastener normal to the sheet.
