All dimensions are given in inches. The key numbers indicate nominal key dimensions. The last two digits give the nominal diam- eter B in eighths of an inch and the digits preceding the last two give the nominal width W in thirty- seconds of an inch. The key numbers with the −1 designation, while representing the nominal key size have a shorter length F and due to a greater distance below center E are less in height than the keys of the same number without the −1 designation.
