The metric thread chart PDF provided on this page is a free download that you can print out and use as a handy reference guide. It contains all the major metric thread sizes and their specifications, including their thread pitch, major diameter, minor diameter, and pitch diameter.
3. Can I use a metric thread chart for non-metric fasteners? No, the ISO metric screw thread chart applies specifically to metric threads. For non-metric threads, like inch-based threads, you will need to consult a different standard, such as Unified National Coarse (UNC) or Unified National Fine (UNF). 4.
This clause specifies the basic profile for ISO general purpose metric screw threads as shown in Figure 1. The dimensions for the various standard pitches are given in Table 1.
The major diameter in our bolt size chart, typically measured in millimetres (mm), refers to the largest diameter of a threaded cylinder, also known as the crest of the thread. This is a critical parameter as it essentially dictates all metric bolt sizes.
