Lightning Bolt & Supply has been servicing North America’s industrial fastener needs for over 25 years. (ref) mm in. AN Size Metal Tube O.D. Metric Fasteners use a thread Pitch. It should be noted that if a thread is stated with a pitch that is not a standard combination of pitch and diameter it is not a fine series pitch thread. Determine the thread pitch in mm using a thread gauge or calipers (typically 1.0, 1.5, or 2.0, but other sizes do exist) Determine the thread O.D (male thread) or I.D (female thread) using calipers. Use of thread sealant is recommended for NPT male and NPT female connection. The second number (0.7) is the pitch which corresponds to the distance between two adjacent threads in millimeters. For example, M5 × 0.35 is simply an ISO metric thread of pitch 0.35 mm, that is, it is a non-standard combination of diameter and pitch (Davies and Yarwood, 1986). Mudge Metric Conversion Chart and Selection Guide (PDF) Metric fastener sizes are specified by diameter, pitch and length, in millimeters (mm). The metric system’s “pitch” is commonly viewed as the reverse of TPI in that it is the “DISTANCE” measured between two adjacent threads. A screw thread in conformity with this International Standard is designated by the letter M followed by the values of the nominal diameter and of the pitch expressed in millimetres separated by the sign x.
