I need to replace the screws that fasten the front plate to the enclosure.
After looking through the manual, the parts list does list a bunch of screw types like #6-32 X 1/4.

However, the screws I need are listed as #6 P.K.
I have no idea what "P.K." means. Does anyone know what #6 P.K. means?

Thanks,
Tony

This is a self tapping sheet metal screw. The "PK" comes from Parker Kalon, the original manufacturer.

Thanks for the reply.
It's strange that they list the screw sizes for all the other screws but for these 9 screws the manual only shows P.K. instead of the actual screw size.

Anyway, appreciate the answer.

#6 designates the diameter of the screw shank. Since they only hold the front panel the length and threads per inch isn't too critical. Simply try some #6 sheet metal screws long enough to go through both the front panel and into the cabinet.

Yeah, I know. Thanks for your input however. I was mainly curious about the "P.K." designation as I have never seen that before. So now I know that is/was a manufacturer and it denotes a self tapping type of screw.
