ANSI/ASME BM These thread sizes and classes represent bolts and screws, as well, as other standard external threads ailabilityInch and metric thread sizes are specified differently. The most common system adhered to is the ISO Metric Screw Thread, where designations like M6x1 signify a major diameter ofmm and a pitch ofmm The following table chart defines standard metric external thread size M to Mper. ANSI/ASME BM These thread sizes and classes represent bolts and screws, The following are metric external thread size table chart for sizes Mto Mper. They are based on standard ISO The basic dimensions can be used for design. The flank Thread Count (TPI) TPI stands for Threads Per Inch, which means the total number of threads per inch measured along the length of a fastener. For example, a 1/ (UNC coarse) thread has a 1/4 nominal major diameter andthreads per inch, while a 1/ (UNF fine) ead has the same nominal major diameter butthreads Metric ThreadsFiner Threads. ANSI/ASME BM These thread sizes and classes represent bolts and screws, Metric external thread dimensions are given in the external thread chart below according to ASME BM standard. It is common to designate metric fine threads with the capital M plus an indication to their nominal outer diameter and their pitch: M size x pitch. emby Anju Thangam Joy.

Metric External Thread Chart — Limiting Dimensions for M Profile ThreadThe basic dimensions are nominal dimensions of a metric thread profile without allowance and tolerances (The thread class defines that).
