Key specifications

Choosing 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. For a different strength level see Hobson Metric Hex Set Screw, Class 8.8, Zinc Plated, M5 to M30.
