Is this self drilling/self tapping screw suitable for use into a F-150 high-strength steel main frame member?

No, go to someplace local who can sell the proper hardness. These are fine for sheet metal on carports.

What is the overall diameter of the head? I need to know if I'll need washers for a 1/2" hole

Dear customer, the overall diameter of the washer head is 12.2-13.5mm. For your 1/2" (12.7mm) hole, we suggest you to use additional washer to make sure your projects work succussfully. Actually you could find flat washer in our shop. Our flat washer price is very competitive. Hope that will help you.

Will a #8 screw work with a #10 washer?

Dear Customer, Yes, #10 flat washer is definitely OK with #8 screws. Hope that will help you. Wish you have a good day.

i need 1600 screws do you have a big box?

Dear Customer, we haven't provided big box containing more than 100 pcs at present. Actually the price with 100 pcs is very competitive in Eastlo. Hope that could help you make your choice. Have a nice day.
