And this is a good way to determine if the bolt is metric or standard. Most bolts come in pretty uniform lengths.
Because this is approximately the same as the Major or Thread diameter the thread diameter measurement can be used for fully threaded bolts.

The diameter of a bolt is the Shank diameter expressed in millimetres for Metric bolts. Because this is approximately the same as the Major or Thread diameter the thread diameter measurement can be used for fully threaded bolts. To measure length start from right below the head including any shank and measure to the tip.
This rule for bolt length is applicable for the motor head socket head and button head types. Only measure the entire length if you are working with the countersunk head design. Measurement of metric bolt should always be done with metric.
Imperial bolt sizes will use fractional and the measurements dont carry over easily at all. If you ask for a 6mm bolt that is 125 long the calculation will have to be preformed and is most confusing in ordering. 36 rows The length of a metric bolt is measured and defined in exactly the same way as.
32 rows Metric Stud Bolt To Nut Size Chart. Thread angle taper and roundness. For standard bolts in the range of M5 M12.
Also called Major diameter. The diameter of a bolt is the Shank diameter expressed in millimetres for Metric bolts. Because this is approximately the same as the Major or Thread diameter the thread diameter measurement can be used for fully threaded bolts.
With metric threads tapping drill size is easy to work out because it is the bolt diameter minus the thread pitch so for example a standard pitch M16 bolt has a pitch of 20mm so the tapping drill size is 16 2 14mm. The table below gives tapping drill sizes for threads corresponding to the thread pitches given in the table on page 3. How to determine the size grade and thread form of a nut or bolt.

And this is a good way to determine if the bolt is metric or standard. Measure the bolt length not including the cap and see if its closer to a fraction of an inch or a nice and round millimeter length that ends in 5 or 0. The length of a bolt is also stated by the measurement from under the head to the end but the length of the thread is determined by the diameter as shown above.
