	They match up perfectly in size & finish. The rivots were .10 each and the punch was $15. ![]()  |

			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
