The Ulitmate Metric Screw Thread Resource: Basic Dimensions, Classes, Tolerances, Formulas, Charts, and Explanations
Classes of threads are differentiated by the amount of tolerance and allowance specified. Indicating gaging is typically mastered at maximum material condition. This is the minimum Pitch diameter tolerance limit for I.D. threads and the maximum Pitch diameters tolerance limit for O.D. threads. BASIC SIZE THREAD CLASS TOLERANCE OVERLAP THREAD ...
The metric thread chart PDF provided on this page is a free download that you can print out and use as a handy reference guide. It contains all the major metric thread sizes and their specifications, including their thread pitch, major diameter, minor diameter, and pitch diameter.
A thread chart is a reference for identifying the types of threads and the suitable replacements for a given product. It is helpful in determining the right thread size when repairing or replacing parts in machinery, tools, and other items with threaded connections.
Metric Thread Size Explained. In our metric screw size chart above, metric thread size is denoted by a series of numbers and letters that encapsulate various dimensions including the major diameter, thread pitch, and thread type.
Screw thread terms and definitions can be found in BS 6528 (identical with ISO5408-1983) and these will be adopted in future standards and revised existing standards.
