ORDERING INFORMATION
When ordering, select the required part number shown in the
Voltage Ratings selection table, then:-
Add K to type number for 1/2" 20 UNF thread, e.g.
TK12 18K.
or
Add M to type number for M12 thread, e.g.
TK12 14M.
Note: Please use the complete part number when ordering and
quote this number in any future correspondance relating to your
order.
