The values listed in the chart above are the recommended values for a class 2 thread fit. The clearance drill sizes listed are the most commonly used sizes.

In our metric screw size chart above, metric thread size is denoted by a series of numbers and letters that encapsulate various dimensions including the major diameter, thread pitch, and thread type. The most common system adhered to is the ISO Metric Screw Thread, where designations like M6x1 signify a major diameter of 6 mm and a pitch of 1 mm.

Below is a single, consolidated reference for comparing common metric diameters or lengths (in mm) with their approximate inch equivalents (“in.”) and the closest common fraction typically used by mechanics. If you see a fastener labeled “M6,” that simply refers to 6 mm.
