    Abstract - (Show below) - (Hide below)

    This International Standard specifies selected sizes for screws, bolts and nuts in the diameter range from 1 mm to 64 mm of ISO general purpose metric screw threads (M) having basic profile according to ISO 68-1.

    These selected sizes are recommended also for general engineering use.

    These screw threads are selected from ISO 261.

    For thread designations see ISO 965-1.
