Using the thinnest possible shims is crucial because it allows for precise adjustments without introducing excessive gaps or misalignments in the machinery being serviced. Thinner shims can help maintain better alignment, which is essential for operational efficiency and equipment longevity. They also reduce the risk of stress concentrations that can lead to premature wear or failure of components.

In terms of machinery alignment and stability, thinner shims accommodate the small, precise adjustments typically necessary in high-precision applications. Employing the correct thickness ensures that the machinery maintains optimal performance levels.

In contexts where only thicker shims are used, it can result in imprecise alignments that can exacerbate wear and vibration issues. Relying on shimming as a means of correcting misalignment should be done with the intent to achieve accurate fits, thereby improving reliability and maintenance regimes.
