A THIN FLAT METAL OR PLASTIC ITEM OF VARIOUS PERIPHERAL SHAPES HAVING A SOLID OR LAMINATED CROSS-SECTION. IT IS DESIGNED TO MAINTAIN A PREDETERMINED DISTANCE BETWEEN TWO SURFACES. FOR ROUND ITEMS WITHOUT A HOLE AND HAVING A SOLID RECTANGULAR CROSS-SECTION USE DISK, SOLID, PLAIN. ITEMS WITH EITHER (1) A SOLID (NOT LAMINATED) CROSS-SECTION, OR (2) A NON-SEPARABLE LAMINATED CROSS-SECTION WITH ONE HOLE CENTRALLY LOCATED, MUST HAVE A THICKNESS LESS THAN 0.006 INCH (0.152 MM) FOR ITEMS LESS THAN 1/4 INCH (6.35 MM) OUTSIDE DIAMETER OR SHORTEST DISTANCE ACROSS PERIPHERAL FLATS, AND LESS THAN 0.016 INCH (0.406 MM) FOR ITEMS 1/4 INCH (6.35 MM) OR MORE OUTSIDE DIAMETER, OR SHORTEST DISTANCE ACROSS PERIPHERAL FLATS. FOR ITEMS WITH THICKNESS GREATER THAN THOSE INDICATED ABOVE, SEE SPACER, PLATE; WASHER, FLAT AND SPACER, RING. WHEN THICKNESS AND/OR OUTSIDE DIAMETER OR SHORTEST DISTANCE ACROSS PERIPHERAL FLATS IS DESIGNATED AS A TOLERANCE DIMENSION, THE MAXIMUM DIMENSION WILL BE USED TO DETERMINE COMPLIANCE.
