ITEM NAME:   WASHER,FLAT
DEFINITION:  A washer having a centrally located hole with a solid or laminated
             cross-section and two flat parallel bearing surfaces. The hole must be
             75 percent or less than the largest dimension and the bearing surface
             finish is greater than 32 microinch (0.8 micrometer). The thickness
             cannot exceed 25 percent of the largest outside dimension. When the
             largest outside dimension is less than 1/4 inch or 6mm, the thickness
             must be 0.006 inches (0.15mm) or greater and for items 1/4 inch (6mm)
             or larger, the thickness must be 0.016 inches (0.4mm) or greater. The
             maximum tolerance is applied to dimensions and used as a determining
             factor. Items with separable lamination use SHIM. For items fabricated
             from ceramic or electrically rated materials by specification or
             industry standards use INSULATOR (1), WASHER. Excludes DISK, VALVE,
             graphite impregnated and lubricated items.
