Metric threads share many characteristics with British threads so caution must be taken when attempting to differentiate the two First if the Metric thread is DIN 7631 it will have a 30 176 chamfer on the male thread the same as a BSPP

Thread classes for bolts sized in inches

2006 10 03 nbsp 0183 32 See also thread classes for bolts sized in metric units Classes of fit are tolerance standards they set a plus or minus figure that is applied to the pitch diameter of bolts or nuts Thus they describe how much bigger or smaller a thread can be than the ideal size specified by the thread series standard The classes of fit used with almost all bolts sized in inches are

UNC UNF Metric Thread Chart Northwest Fastener

Metric fastener threads are described by the pitch rather than the thread density Thread Pitch is the distance from one thread to the next measured from crest to crest Like inch fastener descriptions the thread parameter of metric fastener descriptions comes after the thread diameter The example above has a 12mm thread diameter a 1 75mm thread pitch and a

Metric System amp Specifications Fastenal
