Abstract: A tolerance absorbing spacer for controlling manufacturing dimensional tolerance variation in products made with multiple internal components, each requiring unique dimensional tolerance allowance. This component adjusts and compensates for the resulting overall cumulative component height variation within an assembly of components, sometimes referred to as “stack height” by compensating for the maximum to minimum range of possible assembly heights, compressing and yielding under applied external force until all excess internal clearance is removed, except for a small, and desirable remaining clearance. This component yields and becomes essentially fully plastic, to provide the necessary tolerance adjustment feature only after reaching a predetermined, minimum force which exceeds all applied forces the component could reasonably encounter in service use and below which, the tolerance absorbing spacer remains fully rigid.
