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. TK26 18K.
or
Add M to type number for M16 thread, e.g. TK26 14M.
Note: Please use the complete part number when ordering
and quote this number in any future correspondance relating
to your order.
