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. Metric sizes are the nominal diameter in millimetres; compare the pitch with your nut or tapped hole. Length is measured from under the head to the end of the screw.
