Selecting the right option
Choose the thread form first: the screw and the nut or tapped hole must match in thread form, diameter and pitch. Fine pitch means a finer pitch than the standard coarse thread of the same diameter, so a standard metric nut will not fit. Length is measured from under the head to the end of the screw. Strength figures are the minimum tensile strengths for the class or grade and size range in the Hobson guide, which is a head-marking table, so treat them as the class or grade minimum and not a test result for the screw (manufacturer-stated). For a different strength level see Hobson Metric Hex Set Screw, Class 4.6 UTS, Plain, M16, M20 and M24.
