Selecting the right option
Choose the thread form first: the screw must match its nut or tapped hole in thread form, diameter and pitch. Sizes are nominal diameters in inches; compare the threads per inch with your thread. By convention the length of a socket head cap or button head screw is measured from under the head; the product data does not state the measuring point. Check the key size against the screw in hand, as the product data does not state it.
