02mm

02mm (sometimes written as 0,2 mm or 0.2 mm) is a metric measurement of length equal to two‑tenths of a millimetre. It is used in a variety of technical and industrial contexts to specify very small dimensions, such as the thickness of sheet metal, the diameter of a screw thread, or the size of a drill bit. Because the metric system is globally accepted, 02mm serves as a standard reference point for precision manufacturing, laboratory equipment, and quality control processes.

In the electronics industry, a 02mm drill hole is often employed in printed circuit boards (PCBs) to accommodate thin wire or trace weaves. The designation helps ensure consistency across component manufacturers and facilitates the interchange of parts without the need for conversion. In the automotive sector, 02mm is sometimes applied to describe the thickness of certain thin‑film coatings, which are critical to corrosion resistance and paint adhesion. Designers and engineers routinely reference such fine measurements when specifying tolerances for tight-fitting assemblies.

The measurement also appears in agricultural equipment, where a 02mm groove could refer to the cut width of a seed drill, influencing seed spacing and plant density. Similarly, in the medical field, a 02mm gauge might describe the dimension of needles used for very delicate injections or the thickness of a catheter wall.

Overall, 02mm is a small but essential dimension that finds application in precision engineering, manufacturing, and scientific instrumentation, allowing professionals across multiple disciplines to specify extreme accuracy in material dimensions.
