The screws that I got are the same ones that hold the starter solenoid with the little D in the middle (31498-S8), yet I got marked down because they are not flat tipped. But if you pull up the hardware spreadsheet in the other section and search for fan shroud it has several screws listed for it... AMK does sell 40927-S which has a flat tip and is 3/8 head but no head marking. It is also noted on one of the entries for the fan shroud it has 1/4-20X1/2HH,REC,FLNG 1/2,1/2HEX,THD FRM for FAN SHROUD-MOUNTING BRACKET@RADIATOR,289 W A/C. I'm confused since that says it should be a 1/2 inch head....
