The nominal dimensions given in the table for standard threads comply with Tolerance range 6g for bolt threads Tolerance range 6H for nut threads.

The metric steel and metal threads specified in this catalogue are based on the tolerance ranges given above.

Thread tolerances on plastic standard parts (without steel or metallic inserts) cannot as a rule be maintained for technical reasons.
