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.
