How to determine mm threads
WebFeb 13, 2015 · thread series designation: (UN, UNC, UNF, UNEF, UNS) The thread series is generally relative to the outside diameter of the screw. 20 threads per inch on a 1/4" diameter screw is considered coarse: 1/4-20 UNC. On a 3/4" diameter screw, 20 threads per inch is considered extra-fine: 3/4-20 UNEF. Metric thread sizes are specified by diameter and pitch, which is the space between threads. For the size M6 × 1 mm, the pitch is coarse; while the size M6 × 0.75 mm has a fine pitch. If you don't know the pitch, choose coarse threads; they're the industry standard. For example, a M6 x 1 mm has a 6 mm thread diameter … See more Inch thread sizesare specified by diameter and threads per inch. Diameter is also known as screw size.

WebThe thread pitch is the distance between threads expressed in millimeters (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm. In general smaller fasteners have finer thread so they have lower thread pitch.
