ORDERING INFORMATION

When ordering, select the required part number shown in the
Voltage Ratings selection table, then:-

Add K to type number for 3/4" 16 UNF thread, e.g. DK24 16FCK
or
Add M to type number for M16 thread, e.g. DK24 14FCM.
Note: Please use the complete part number when ordering

and quote this number in any future correspondance relating
to your order.
