Re: Nova TCS Switch & Wiring Gutter 101

Hello Sam,

Normative Observable Practice is
Part number 9419320
Indented Head 10-16x3/8 5/16 AF .40 OD
Hex Washer Head Tapping Screw

Common to have a triangle inside of 2 Circles for a head marking. Magnesium Phosphate. Black to dark gray.

I can not rule out that zinc was also used. However I do not believe Zinc is original. This part number is sold as repro in zinc.

Does that help?
Greg
