Special Features:

Outer edge is chamfered beginning 0.060 in. From top at 40 degrees to depth of 0.088 in. From top to outer diameter for lower part of 5.375 in.; inner edge at top is rounded to radius of 0.125 deg; also has saw cut 0.030 in. Wide at 45 degrees through washer

Properties:

An insulator that is essentially thin and flat, with one through hole centrally located. The general shape may vary by the addition of features such as beveled edges, indented surfaces, through hole keys, and/or peripheral flats. The thickness measured between the two parallel bearing surfaces must not exceed 25 percent of the outside diameter or the shortest distance between peripheral flats. The thickness measured between the two parallel bearing surfaces must not exceed 25 percent of the outside diameter or the shortest distance between peripheral flats. Excludes items with more than one hole. See also insulator, disk; insulator, bead; insulator, bushing; and insulator, plate
