| 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 ( .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 . 6 inches ( .15mm) or greater and for items 1/4 inch (6mm) or larger, the thickness must be . 16 inches ( .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. |
