The basic dimensions are nominal dimensions of a metric thread profile without allowance and tolerances (The thread class defines that). They are based on standard ISO 68-1. The basic dimensions can be used for design. However, for manufacturing and machining, you need the allowable range of each dimension.
Thread type: M - ISO Metric Coarse Thread DIN 13. Overview table, specification and cross section. With our "ISO metric thread M to DIN 13" table, you always have all the important key data for this thread type to hand and clearly arranged at a glance.
The metric ISO standard thread is standardized according to the DIN 13-1 standard, which covers standard threads with an outer diameter of 1 to 68 mm. This standard was first defined back in 1949, but has been revised and updated many times since then.
Metric ISO thread. Tolerance fields 6g / 6H. Description. The limiting sizes for standard threads given in the table comply with. tolerance field 6g for bolt threads 6H for nut threads. The metric steel and metal threads specified in this catalogue are based on the tolerance fields given above.
