Often screw sizes will also tell you the number of threads a screw has by adding a dash and the number of threads for example 4 40 is a size four screw with 40 threads but that can vary so we haven t included it here A screw s major diameter shows the screw s diameter as measured from tip to tip of its threads and in this table we ve included the minimum and maximum Metric thread calculator to calculate external and internal metric thread dimensions including major diameter minor diameter pitch diameter and thread tolerance according to ISO 724 and ISO 965 standards There are two calculation options available general engineering use or custom use In general engineering use calculations can be done by selecting a standard This is also referred to as the quot major quot diameter in the information below It indicates the diameter of smooth walled hole that a male thread e g on a bolt will pass through easily to create a well located connection to an internally threaded component e g a nut on the other side That is an M6 screw has a nominal outer diameter of 6 millimetres and will therefore be a well located co 29 rows nbsp 0183 32 Tap size Basic major dia mm Basic major dia inch mm per thread Drill size mm 66 rows nbsp 0183 32 The design principles of ISO general purpose metric screw threads quot M quot series
