Toleranties Volgens Iso
General tolerances for linear measures and level squares with four tolerance classes are useful for simplifying drawings. By choosing the tolerance class precision levels common in workshops should be taken into account.
The “coarse” pitch is the commonly used default pitch for a given diameter. In addition, one or two smaller “fine” pitches are defined, for use in applications where the height of the normal “coarse” pitch would be unsuitable (e.g., threads in thin-walled pipes). The terms “coarse” and “fine” have (in this context) no relation to the manufacturing quality of the thread.In addition to coarse and fine threads, there is another division of extra fine, or “superfine” threads, with a very fine pitch thread.
Superfine pitch metric threads are occasionally used in automotive components, such as suspension struts, and are commonly used in the aviation manufacturing industry. This is because extra fine threads are more resistant to coming loose from vibrations.
Spanner (wrench) sizes Below are some common spanner (wrench) sizes for metric screw threads. Hex head widths (width across flats, spanner size) are for 934 hex nuts and hex head bolts., 2007-03-05, Version 1.3.
