*Note–When Installing Grommets:

  1. It is desirable that the burr side of the hole be opposite the grommet entry.
     
  2. The surface condition of the hole edge has a definite bearing on the ease with which a grommet can be inserted and how well it will fit and hold until the screw is driven. For instance, the smaller end of the hole size range, when used with a porcelainized surface, can provide a leak proof fit. Indicated hole sizes are final, i.e.: after painting, enameling, etc. For hole sizes that will provide the best combinations of easy installation and secure fit, the following can serve as a general guide:

    Surface Condition Hole Size

    Porcelain: Small end of indicated range
    Enamel: Slightly below mid range
    Paint: Middle of indicated range
    Plastic Panel: Middle of indicated range
    Raw Metal: Large end of indicated range
     
  3. Driving torque and stripping torque will generally increase with decreasing hole sizes and increasing panel thickness.
NOTE: †Driving and stripping torques will vary depending on panel hole size, panel thickness, and screw type used. In all cases, however, the stripping torque is  at least 250% of the driving torque.
